This release doesn't have any major new features, what it has are many small to medium additions, bugfixes, and breaking changes.

The biggest changes are:

  • prefix types: using custom pointer types instead of references.

  • Flattening of abi_stable module hierarchies, leaving many items only at the submodule level (abi_stable::foo::*).

Changelog

This is copied from the Changelog.md file.

Changes

Rewrote how prefix types work. now they aren't by reference, they use static-reference-like types generated for each prefix type (those types have a _Ref suffix by default).

Flattened many module hierarchies in abi_stable, leaving many of those items only exposed where they used to be reexported.

Now #[repr(C, packed)] prefix types are forbidden.

Added a PrefixRef pointer type, which is what the *_Ref types wrap, used as the pointer to the prefix of every prefix type.

Now the #[sabi(kind(Prefix))] takes two optional arguments, prefix_ref and prefix_fields, defaulting to prefix_ref = "<DerivingType>_Ref" and prefix_fields = "<DerivingType>_Fields".

Made the root_module_loader function(declared with the #[export_root_module] attribute) be able to return anything that implements the new IntoRootModuleResult trait, including Result<_, RBoxError_>.

Declared the RootModuleError type and LibraryError::RootModule variant for the errors returned by root module loaders.

Defined the abi_stable::library::development_utils module with helper items for use while developing a dynamic library.

Made Constructor, MovePtr, RRef, NulStr, and StaticRef use NonNull instead of a raw pointer, this allows Options wrapping them to be ffi-safe.

Split off SharedStableAbi trait from StableAbi, now there's PrefixStableAbi and StableAbi, both of which only have GetStaticEquivalent_ in common.

Renamed WithMetadataFor to PrefixMedata, and added accessors for its fields.

Removed PrefixTypeTrait::into_with_metadata method,added PrefixFields and PrefixRef assoc types.

Added staticref macro for declaring StaticRef consts,added StaticRef::leak_value constructor.

Added ImmutableRef marker trait for reference-like types.

Made LateStaticRef generic over the pointer it wraps, using the ImmutableRef trait.

Renamed LateStaticRef::<&T>::initialized to from_ref.

Added the LateStaticRef::<PrefixRef<P>>::from_prefixref constructor.

Added PrefixRefTrait trait for ffi-safe pointers to prefixes.

Added the PointsToPrefixFields marker type, and PrefixRefTrait::PREFIX_FIELDS associated constant to construct it, this type is required for calling LateStaticRef::from_prefixref.

Made RootModule trait have an additional PrefixRefTrait supertrait.

Added the abi_stable::for_examples module, with types used in documentation examples.

Added Send + Sync supertraits to TypeChecker and ExtraChecks

Defined the RMut type to rewrite how #[sabi_trait] passes the method receiver.

Added sabi_as_rref and sabi_as_rmut methods to RObject and DynTrait to get RRef and RMut to the wrapped value.

Made abi_stable testable with miri

Bumped the minimum supported Rust version to 1.41.0.

Updated these public dependencies:

  • core_extensions to "0.1.18"
  • libloading to "0.6.4"
  • parking_lot to "0.11.0"
  • lock_api to "0.4.1"
  • crossbeam-channel to "0.5.0"
  • serde and serde_derive to "1.0.117"

Fixed the lack of # Unsafe docs for some unsafe traits.

Made (small) improvements to all of the documentation.

Added docs to the module that #[sabi_trait] generates, and hid methods in *_MV types (they were not supposed to be public).

Added generated docs for nonexhaustive enums, unhid the generated items, and made the generated constructors #[doc(hidden)} when the variants are.

Removed parameters of assert_nonexhaustive, using std::any::type_name internally instead.

Hid nonexhaustive_enum::GetVTable::VTABLE_REF

Added support for pinning RBox.

Added std::iter::*,Future,Hasher,Error,std::io::*, and std::fmt::Pointer impls for RBox.

Changed impl_get_type_info macro to take a :ty parameter.

Made the fields in InlineStorage types public.

Added associated constants to construct some types in abi_stable::marker_type.

Fixed handling of unsafe trait in #[sabi_trait], before this the unsafe was removed in the generated code.

Fixed an unsoundness bug where LateStaticRef<T> implemented Send + Sync even if T didn't.

Fixed an unsoundness bug where the RBpxErrpr returned from checking the layout of a library could contain references into the unloaded library, by using a new RBorError_::to_formatted_error method to stringify the error.

Changed RBox::{from_fmt, from_debug, to_formatted_error} to take references.

Added check to the declare_root_module_statics macro to safeguard against passing Self.

Fixed(?) the variance of type parameters in #[sabi_trait] generated trait object to be covariant.

Fixed RMutex::get_mut, which caused a memory leak.

Fixed RRwLock::get_mut, which caused a memory leak.

Fixed exporting of abi_stable::prefix_type::BoolArrayIter, before this it was not shown in the docs.

Made MovePtr<T> implement Send and/or Sync when T does.

Added RSliceMut::as_mut_ptr method

Removed the RSliceMut::into_slice_mut method (it was marked for deprecation)

Implemented Send and Sync for the RString and RVec iterators.

Made prefix_type::panic_on_missing_field_val private

Made TagErrorVariant private.
