Fixed

• Allow to run bindgen -v without an input header argument.

Added

• Added the ParseCallbacks::header_file callback which runs on every filename passed to Builder::header.
• Added the CargoCallbacks::new constructor which emits a cargo-rerun line for every input header file by default.
• Added the CargoCallbacks::rerun_on_header_files method to configure whether a cargo-rerun line should be emitted for every input header file.

Changed

• The --wrap-static-fns feature was updated so function types that has no argument use void as its sole argument.
• CargoCallbacks is no longer a unit-like struct and the CargoCallbacks constant was added to mitigate the breaking nature of this change. This constant has been marked as deprecated and users will have to use the new CargoCallbacks::new method in the future.

Removed

Fixed

• Allow compiling bindgen-cli with a static libclang.
• Emit an opaque integer type for pointer types that don't have the same size as the target's pointer size.
• Avoid escaping Objective-C method names unless they are Self, self, crate or super.

Security

Fixed

• Fixed errors on the windows artifact build process.

Added

• The system ABI is now supported as an option for the --override-abi flag.
• The allowlist_item method and the --allowlist-item flag have been included to filter items regardless or their kind.
• Include installers as release artifacts on Github.

Changed

• The Clone implementation for _BindgenUnionField has been changed to pass the incorrect_clone_impl_on_copy_type Clippy lint.
• The c_unwind ABI can be used without a feature gate for any Rust target version equal to or greater than 1.71. This comes as a result of the ABI being stabilised (in Rust 1.71).
• Formatting changes when using prettyplease as a formatter due to a new prettyplease version.
• Avoid generating invalid CStr constants when using the --generate-cstr option.

Removed

• The extra_assert and extra_assert_eq macros are no longer exported.

Fixed

• Bindgen no longer panics when parsing an objective-C header that includes a Rust keyword that cannot be a raw identifier, such as: self, crate, super or Self.

Removed

• Revert source order sorting (#2543) due to correctness regressions #2558.

Added

• Added the --generate-cstr CLI flag to generate string constants as &CStr instead of &[u8]. (Requires Rust 1.59 or higher.)
• Added the --generate-shell-completions CLI flag to generate completions for different shells.
• The --wrap-static-fns option can now wrap va_list functions as variadic functions with the experimental ParseCallbacks::wrap_as_variadic_fn method.
• Add target mappings for riscv32imc and riscv32imac.
• Add the ParseCallbacks::field_visibility method to modify field visibility.

Changed

• Non-UTF-8 string constants are now generated as references (&[u8; SIZE]) instead of arrays ([u8; SIZE]) to match UTF-8 strings.
• Wrappers for static functions that return void no longer contain a return statement and only call the static function instead.
• The --wrap-static-fns option no longer emits wrappers for static variadic functions.
• Depfiles generated with --depfile or Builder::depfile will now properly generate module names and paths that include spaces by escaping them. To make the escaping clear and consistent, backslashes are also escaped.
• Updated bitflags dependency to 2.2.1. This changes the API of CodegenConfig.
• Prettyplease formatting is gated by an optional, enabled by default Cargo feature when depending on bindgen as a library.
• Items are now parsed in the order they appear in source files. This may result in auto-generated _bindgen_* names having a different index.
• Use default visibility for padding fields: Previously, padding fields were always public. Now, they follow the default visibility for the type they are in.
• Compute visibility of bitfield unit based on actual field visibility: A bitfield unit field and its related functions now have their visibility determined based on the most private between the default visibility and the actual visibility of the bitfields within the unit.

Removed

• Remove redundant Cargo features, which were all implicit:

  • bindgen-cli: env_logger and log removed in favor of logging
  • bindgen (lib):
    • log removed in favor of logging
    • which removed in favor of which-logging
    • annotate-snippets removed in favor of experimental

• Prettyplease is available as a Formatter variant now.

Fixed

• The Builder::rustfmt_bindings method was added back and tagged as deprecated instead of being removed.
• Broken documentation links were fixed.

Added

• Added the Builder::default_visibility method and the --default-visibility flag to set the default visibility of fields. (#2338)
• Added the --formatter CLI flag with the values none, rustfmt and prettyplease to select which tool will be used to format the bindings. The default value is rustfmt. (#2453)
• Added the Builder::formatter method and the Formatter type to select which tool will be used to format the bindings. (#2453)
• Added the Builder::emit_diagnostics method and the --emit-diagnostics flag to enable emission of diagnostic messages under the experimental feature. (#2436)
• Added support for the "efiapi" calling convention (#2490).
• Added the ParseCallbacks::read_env_var method which runs everytime bindgen reads and environment variable. (#2400)
• Added the ParseCallbacks::generated_link_name_override method which allow overriding the link name of items. (#2425)
• Add support for C enums when generating code while using the --wrap-static-fns feature. (#2415)

Changed

• Static functions with no arguments use void as their single argument instead of having no arguments when the --wrap-static-fns flag is used. (#2443)
• The source file generated when the --wrap-static-fns flag is enabled now contains #include directives with all the input headers and all the source code added with the header_contents method. (#2447)
• The source file generated when the --wrap-static-fns flag no longer uses asm labeling and the link name of static wrapper functions is allowed to be mangled. (#2448)
• The documentation of the generated type aliases now matches the comments of their typedef counterparts instead of using the comments of the aliased types. (#2463)
• The Builder::rustfmt_bindings methods and the --no-rustfmt-bindings flag are now deprecated in favor of the formatter API. (#2453)

Removed

• The following deprecated flags were removed: --use-msvc-mangling, --rustfmt-bindings and --size_t-is-usize. (#2408)
• The Bindings::emit_warnings and Bindings::warnings methods were removed in favor of --emit-diagnostics. (#2436)
• Bindgen no longer generates C string constants that cannot be represented as byte slices. (#2487)

Added

• Added a new set of flags --with-derive-custom, --with-derive-custom-struct, --with-derive-custom-enum and --with-derive-custom-enum to add custom derives from the CLI.
• Added the --experimental flag on bindgen-cli and the experimental feature on bindgen to gate experimental features whose implementation is incomplete or are prone to change in a non-backwards compatible manner.
• Added a new set of flags and their equivalent builder methods --wrap-static-fns, --wrap-static-fns-suffix and --wrap-static-fns-path to generate C function wrappers for static or static inline functions. This feature is experimental.

Changed

• Fixed name collisions when having a C enum and a typedef with the same name.
• The ParseCallbacks::generated_name_override method now receives ItemInfo<'_> as argument instead of a &str.
• Updated the clang-sys crate version to 1.4.0 to support clang 15.
• The return type is now omitted in signatures of functions returning void.
• Updated the clap dependency for bindgen-cli to 4.
• Rewrote the bindgen-cli argument parser which could introduce unexpected behavior changes.
• The ParseCallbacks::add_derives method now receives DeriveInfo<'_> as argument instead of a &str. This type also includes the kind of target type.

Added

• new feature: process_comments method to the ParseCallbacks trait to handle source code comments.

Changed

• Only wrap unsafe operations in unsafe blocks if the --wrap_unsafe_ops option is enabled.
• Replace the name: &str argument for ParseCallbacks::add_derives by info: DeriveInfo.
• All the rust targets equal or lower than 1.30 are being deprecated and will be removed in the future. If you have a good reason to use any of these targets, please report it in the issue tracker.

Removed

• The following deprecated methods and their equivalent CLI arguments were removed: whitelist_recursively, hide_type, blacklist_type, blacklist_function, blacklist_item, whitelisted_type, whitelist_type, whitelist_function, whitelisted_function, whitelist_var, whitelisted_var, unstable_rust.

Added

• new feature: --override-abi flag to override the ABI used by functions matching a regular expression.
• new feature: allow using the C-unwind ABI in --override-abi on nightly rust.

Changed

• Regex inputs are sanitized so alternation (a|b) is handled correctly but wildcard patterns (*) are now considered invalid. The .* pattern can be used as a replacement.
• the ParseCallbackstrait does not require to implement UnwindSafe.
• the Builder::parse_callbacks method no longer overwrites previously added callbacks and composes them in a last-to-first manner.
• any generated rust code containing unsafe operations inside unsafe functions is wrapped in unsafe blocks now.

Fixed

• Various issues with upcoming clang/libclang versions have been fixed.

Released 2022/10/16

Added

• new feature: --sort-semantically flag to sort the output in a predefined manner (#1743).
• new feature: Bindgen::emit_warnings method to emit warnings to stderr in build scripts.
• new feature: --newtype-global-enum flag to generate enum variants as global constants.
• new feature: --default-non-copy-union-style flag to set the default style of code used to generate unions with non-Copy members.
• new feature: --bindgen-wrapper-union flag to mark any union that matches a regex and has a non-Copy member to use a bindgen-generated wrapper for its fields.
• new feature: --manually-drop-union flag to mark any union that matches a regex and has a non-Copy member to use ManuallyDrop.
• new feature: --merge-extern-blocks flag to merge several extern blocks that have the same ABI.
• new feature: --no-size_t-is-usize flag to not bind size_t as usize.
• new feature: Builder implements Clone.

Changed

• clap and regex have been updated, new msrv is 1.57.
• The --enable-function-attribute-detection flag is also used to detect diverging functions so the generated bindings use ! as the return type.
• The --size_t-is-usize flag is enabled by default.
• Unused type aliases for <stdint.h> types are no longer emitted.
• The blocklist options now can be used to block objective-C methods.
• The core::ffi module is used the sized raw integer types instead of std::os::raw if the Rust target version is 1.64 or higher and the --use-core flag is enabled.
• The bindgen CLI utility must be installed using cargo install bindgen-cli now.
• Using bindgen as a library no longer pulls clap and any other CLI related dependencies.

Added

• New command line flag to allow disabling untagged unions (#1789).

Fixed

• Rust method wrappers are not emitted for blacklisted functions (#1775).
• Fixed function signatures in some edge cases involving Objective-C or __stdcall (#1781).

Released 2020/03/10.

Changed

• clang-sys and cexpr have been updated (#1741 and #1744).
• Runtime of some commands has been improved (#1737)
• Some error messages have been improved (#1734).

Released 2020/02/03.

Added

• Opt-in to convert size_t to usize again (#1720).

Released 2020/02/02.

Added

• Support for wasm_import_module. (#1691).
• non_exhaustive feature is now stable (#1698).
• Various objective-C improvements (#1702).

Added

• Added newtype enum style, much like bitfield but without the bitwise ops (#1677).
• Added support for MaybeUninit rather than mem::uninitialized() (#1666).
• Allowed static linking (#1620) behind a feature. Note that if you're using default-features = false, you probably want to use the "runtime" feature to get the same behavior as before.

Changed

• Use c_void from core when --use-core is specified and available (#1634).
• Various dependencies and features are non-default now (like regex unicode features).

Fixed

• Refactored the way layout of wchar_t is computed. This is a breaking change since IntKind::WChar (exposed in ParseCallbacks) no longer needs a size member. #1596

Added

• Bindgen now reads RUSTFMT in the environment to try to find a suitable rustfmt binary. #1602

Released 2019/07/01.

Added

• Fixed pointers to Objective C blocks #1582.

• Various bindgen auto-generated types are now constructible in const fn contexts #1571

• It is possible to generate #[non_exhaustive] enums for rust nightly targets. #1575

• It is possible to avoid building clap now if you're using bindgen as a library. #1581.

Added

• Various bindgen auto-generated types are now constructible in const fn contexts #1571

• It is possible to generate #[non_exhaustive] enums for rust nightly targets. #1575

• It is possible to avoid building clap now if you're using bindgen as a library. #1581.

Released 2019/05/22

Changed

• Bindgen now has an option to generate array arguments as pointer to the array, not to the element (so void foo(int arr[2]) would be generated as arr: *mut [c_int; 2] rather than arr: *mut c_int. Thanks @elichai! #1564.

Released 2019/05/16

Fixed

• Bindgen will not emit #[link_name] attributes in win32 and macos for C functions and constants where it can detect it's not needed (thanks @michaelwoerister!). #1558

Changed

• Bindgen will no longer use hashbrown internally, and will use fxhash and std::HashMap. This is equivalent for newer rustcs since hashbrown was merged in libstd, and the performance difference should be close to zero for older rustcs.

Released 2019/03/27

Added

• BINDGEN_EXTRA_CLANG_ARGS environment variable was added (thanks @jhwgh1968!). #1537

Fixed

• Bindgen will properly name parameters inside nested function pointer declarations (thanks @flowbish!). #1535

Changed

• Derive code was greatly improved by @jethrogb. #1540
• Derive analysis now handles trivial types more gracefully. #1492
• clang-sys was updated by @eclipseo. [#1539][]
• bindgen should now get include paths correctly even when --target is specified. The detect_include_paths option can be used to opt-out of this behavior.

Released 2019/03/06

Fixed

• Bindgen will properly lay out types that use reference members. #1531

Released 2019/03/04

Changed

• Default rust target was changed to 1.33, which means that bindgen can get much more often the layout of structs right. #1529

Fixed

• Bindgen will output repr(align) just when needed for unions. #1498

Released 2020/11/13

Added

• Backported BINDGEN_EXTRA_CLANG_ARGS support per request (#1910).

Released 2019/02/25

Changed

• Allowed to build with which 1.0.

Released 2019/02/22

Fixed

• @flowbish fixed code generation for nested function prototypes. #1508
• Some complex C++ constructs no longer panic on code generation #1513
• Implicit template parameters are now appended to base classes #1515
• @flier fixed single-argument block pointers #1519
• Bindgen won't panic when parsing an undeduced auto type #1525

Released 2019/02/02

Changed

• @luser improved the error message when rustfmt cannot be found #1501

Fixed

• Reverted clang-sys update for regressions #1505

Released 2019/01/19

Changed

• #pragma pack(n) is now translated to #[repr(C, packed(n))] when targeting Rust 1.33+. #537

• Bitfield enums now use #[repr(transparent)] instead of #[repr(C)] when targeting Rust 1.28+. #1474

Fixed

• #[repr(packed)] is now properly added if the struct only contains a vtable. #1495

• clang-sys should now more accurately find libclang versions when multiple of them are available. #1489
