What's Changed

We now support the zlib 1.3.2 API, including deflateUsed and various symbols suffixed by _z to indicate that they use usize for lengths. That is mostly useful on targets where c_ulong is only a 32-bit integer.

• add deflateUsed by @folkertdev in #534
• add {compress, uncompress, etc.}_z variants that take usize for lengths by @folkertdev in #535

Highlights

A while ago a bug was reported in zlib-rs #459, which turned out to also exist in zlib-ng. zlib-ng has now fixed the bug and made a new release, and we're following suit here. This fix can change the output of compression slightly.

• the zalloc_rust and zalloc_rust_calloc functions are behind the rust-allocator feature by @alexanderkjall in #476
• add test for deterministic deflate output by @folkertdev in #461
• fix compilation errors for 'cargo test --all-features' by @alexanderkjall in #477
• Run all the gz tests when building on macOS by @brian-pane in #479
• ensure that all-features and --no-default-features builds by @folkertdev in #480

breaking changes

libz-rs-sys

• functions that used extern "C-unwind" before now use extern "C". This helps when building zlib-rs as a C library, because unwinding from rust into C is UB. Now, if a panic does occur in the rust code, it will abort the program at the FFI boundary rather than unwind into C code. If you do really need unwinding in rust code, we suggest using flate2 or using zlib-rs directly.

zlib-rs

• the internals are no longer publicly exposed. If you were using some unstable symbol before, and it is no longer exported, but you do believe it would be reasonable for us to provide it, let us know.
• the uncompress_slice function was renamed to decompress_slice

other highlights

• the gz* functions are now included in the main crate. Thanks again to @brian-pane for implementing these.
• overall we now provide all public symbols that zlib-ng provides (e.g. inflateBack was added). The gzprintf and gzvprintf functions need nightly though.
• improved avx512 support.
