derive_builder_core

• Accept field(ty = "...") as an alias for field(type = "...") in preparation for moving to syn 2.0, which doesn't allow the use of keywords as meta item paths. #306

• Bump MSRV to 1.56.0
• Add build_fn(error(validation_error = <bool>)) to disable generation of ValidationError within the builder's error so that alloc::string is avoided.
• Add feature alloc for controlling linking of alloc crate during no_std. This way users can use no_std without providing a global_allocator.
• Make try-setters inherit strip_option from setter for try_setter. Using these settings together previously caused a compile error #284

• Produce error when default is used with field(type = "...") rather than silently ignoring default #269
• Add support for crate = "..." to support re-export scenarios #274

• Allow restricted visibility using vis = "..." for builders, build methods, setters, and fields #247
• Allow specifying the type of a builder field using #[builder(field(type = "..."))] #246
• Allow specifying how a builder field is built using #[builder(field(build = "..."))] #246
• Update darling, proc-macro2, syn, and quote dependencies #250

• Forward allow and cfg attributes from the deriving struct to the builder and its impl block #222
• Support passing attributes to the builder struct using #[builder_struct_attr(...)] #241
• Support passing attributes to the builder struct's inherent impl block using #[builder_impl_attr(...)] #241

• Support shorthand and long-form collection setters; #[builder(setter(each = "..."))] and #[builder(setter(each(name = "...")))] #234
• Allow collection setters to be generic over Into using `#[builder(setter(each(name = "...", into)))] #234 and #214
• Allow specifying attributes for builder fields and setters using #[builder_field_attr(...)] and #[builder_setter_attr(...)] #237

Note: This version didn't have anything that clearly required a minor version increase; however, given the amount of time and number of commits since last publication a conservative approach was taken.

• Don't include derive_builder_core in derive_builder so that no_std builds #206

• Updated all dependencies #138

Fixed

• unused_mut lint (variable does not need to be mutable) #104

Fixed

• for generic structs, apply the T: Clone type bound in builder impl instead of struct definition #91
• only emit the T: Clone type bound when it is actually needed, i.e. mutable/immutable pattern, but not owned pattern.

Added

• pre-build validation

Added

• derive traits on builder struct

Added

• try_setters

Fixed

• setter(skip) honors struct-inherited and explicit defaults #68

Added

• Bindings to abstract over libstd/libcore

Changed

• Use bindings: Bindings instead of no_std: bool

Fixed

• support generic references in structs #55
• no_std support #63

Added

• struct default
