  • Add new macros attributes, without compiler support (by @LukeMathWalker)
  • Add support for MaybeUninit (by @LukeMathWalker)
  • Add support for UnsafeCell (by @LukeMathWalker)
  • Add support for arrays with const generic length (by @LukeMathWalker)
  • Simplify ManuallyDrop to T (by @LukeMathWalker)
  • Implement a first version of null-pointer optimization (by @LukeMathWalker)
  • Add parameter names to function pointer declarations when we have them on the Rust side (by @LukeMathWalker)
  • Add type-level simplifications to handle null pointer optimization (by @LukeMathWalker)
  • Add support for simple function pointers (by @LukeMathWalker)
  • Make enum variant prefix configurable (by @LukeMathWalker)
  • Add support for inherent associated constants (by @LukeMathWalker)
  • Handle type aliases (by @LukeMathWalker)
  • Add support for str and char constants. Broaden our test suite for computed constants and other numeric types (by @LukeMathWalker)
  • Add support for repr transparent (by @LukeMathWalker)
  • Include private fields in emitted definitions (by @LukeMathWalker)
  • Add support for unions (by @LukeMathWalker)
  • Add an underscore to Rust variant names and fields that are also keywords in C or C++ (by @LukeMathWalker)
  • Handle 'Self' in structs and enums. Sort type definitions in source order. (by @LukeMathWalker)
  • Add support for standalone constants (by @LukeMathWalker)
  • Emit monomorphised versions of generic types when used with concrete parameters in function signatures (by @LukeMathWalker)
  • Add support for function arguments as expected by the 'both' style (by @LukeMathWalker)
  • Emit C++-compatible headers for enums and tagged unions (by @LukeMathWalker)
  • Make ZST more precise by matching on full path and package id. Test all known variants. (by @LukeMathWalker)
  • Rough support for fieldless enums and tagged unions (by @LukeMathWalker)
  • Add support for documentation config options (by @LukeMathWalker)
  • Add support for generating struct definition out of repr(C) Rust structs (by @LukeMathWalker)
  • Make sorting configurable, either by name or by source order. (by @LukeMathWalker)
  • Support for statics (by @LukeMathWalker)
  • Take generics into account when generating the C name of monomorphised generic Rust types (by @LukeMathWalker)
  • Emit forward declarations for any user-defined type. Stepping stone (by @LukeMathWalker)

  • Collect exported symbols, be they functions or statics (by @LukeMathWalker)
  • Identify the target crate and compute its JSON documentation (by @LukeMathWalker)

🐛 Bug Fixes

  • Emit a blank line between braces for struct definitions with no fields (by @LukeMathWalker)
  • Use typedef union for opaque unions (by @LukeMathWalker)
  • Use GlobalItemId to ensure correct cross-crate resolution of items and docs (by @LukeMathWalker)
  • Emit type definitions in topological order to ensure all types have their by-value dependencies defined beforehand (by @LukeMathWalker)
  • Use the correct style for pointer fields in struct definitions (by @LukeMathWalker)
  • Add trailing new line to header docs when cbindgen does (by @LukeMathWalker)
  • Coverage report now works as expected (by @LukeMathWalker)
  • Honor export attribute when emitting the symbol file (by @LukeMathWalker)

📚 Documentation

🧪 Testing

  • Mark lifetime_arg as passing (by @LukeMathWalker)
  • Exercise generic monomorphisation with and without default type parameters (by @LukeMathWalker)
  • Enhance ui-tests translate-config to emit a granular report on which tests use unsupported cbindgen configuration options (by @LukeMathWalker)
  • Mark more cbindgen tests as passing (by @LukeMathWalker)
  • Speed up config translation by compiling once rather than going through cargo run for each discovered cbindgen.toml file (by @LukeMathWalker)
  • After config translation, report only which files have changed (by @LukeMathWalker)
  • Add a new mechanism to automatically translate a cbindgen config file into a cheadergen one. Keep track of ignored fields. (by @LukeMathWalker)
  • Warm up rustdoc cache ahead of test execution, thus minimizing contention (by @LukeMathWalker)
  • Bring back the cheadergen custom test suite with a failing test (by @LukeMathWalker)
  • Use cheadergen in tests, rather than cbindgen. Track which tests are expected to fail/succeeds. (by @LukeMathWalker)
