Changelog

Sourced from bindgen's changelog.

0.66.0

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.

0.65.1
