0.8.2

Fixed

• don't duplicate concretized bounds on DispatchSet impls

0.8.1

Added

• Derive Wide and NulTerminatedBuf for #[repr(transparent)] structs with multiple fields

Changed

• Emit special-type identity checks once per derive or FFI expansion.
• Rename NulTerminatedBuf::Data to NulTerminatedBuf::Header.
• lower ManuallyDrop<T> as T::CType when T is NoDrop.
• Require Wide implementors to be dynamically sized types.

Removed

• remove UnsafeCell impls which relied on unsychronized access.
• remove #[repr_c(as(T))] feature which relied on false RustSpec.

0.8.0

Added

• Parameterize wide pointer carriers by unsized Wide pointee types.
• Support UnsafeCell<T> and Cell<T> in C-compatible representations.
• Implement CType for ManuallyDrop<T> and represent it as ManuallyDrop<T::CType>.

Changed

• Rename CSlice/CSliceMut/CBoxedSlice to CWideRef/CWideRefMut/CWideBox/CWideBoxCell.
• Rename the mutable carrier const param from RESTRICTED to EXCLUSIVE and remove its default.
• Require opaque types to have the opaque RustSpec with #[rust_spec(opaque)].
• Set the MSRV to 1.99 because of the UnsafeCell transmutation guarantees.
• Remove the Copy supertrait requirement from CFnArg and CFnReturn.

Fixed

• Corrected (de)serialization of ManuallyDrop and MaybeUninit

Removed

• cell::InteriorMut was removed because using UnsafeCell::get is no longer required

0.7.4

Added

• delegate notable trait impls for OwnedExternType to matching impls on ExternType.

Fixed

• Resolve associated item paths FFI function signatures.
• don't allow #[derive] on extern type declarations.

0.7.3

Added

• Add implied Sized bound to params in slice-like DST tails.

Changed

• implement RustSpec for synthesized views manually.

0.7.2

Added

• implement CType for robust Options, Results and derived types with stable layout.
• Add the transparent CRef<T> carrier for shared references to thin values.

Fixed

• Reject niches, validation, and custom Drop in repr delegation

0.7.1

Added

• Add conversions and derives for co3::ffi types and make their use portable

0.7.0

Added

• Add decode_unchecked to decode C-compatible values without validating them.
• Handle types with custom Drop implementations via RustSpec::Drop axis.
• Support encoding CString and custom nul-terminated aggregate types.
• Support #[repr_c(transparent)] which uses inner type's CType
• Generate C-compatible wrappers for bool and Ordering.

Changed

• Model aliasing explicitly in C ABI carriers CRefMut and CSliceMut.
• Rename the niche derive setting from NICHE_VALUE to NICHE.
• Separate header and data handling for Wide types.

Removed

• Restrict Wide implementations to custom slice-like DSTs to avoid undefined behavior.

0.6.0

Added

• Support #[unpack] on method receivers and raw pointers to wide types.
• Implement Unpack2 for raw and NonNull pointers to wide types.
• Derive Wide for eligible #[repr_c(identity)] dynamically sized structs.

Changed

• Change Wide API to take raw pointers instead of references.
• Move conversion store structs, including ArrayStore, from stored to sync.
• Use CBoxCell types as the C-compatible representations of interior mutable boxes.

Fixed

• Correct conversion and borrowing of interior mutable slices and boxes.

0.5.3

Added

• Support #[repr_c(as(T))] to delegate owned conversions through Into<T> and TryFrom<T>.
• Generate an OwnedType = Box<Type> alias for opaque types in ffi! export declarations.
