Release Notes

mozilla/uniffi-rs (uniffi_build)

v0.30.0

Compare Source

⚠️ Breaking Changes ⚠️

• UDL-based trait interfaces must now be wrapped with the #[uniffi::trait_interface] attribute.
• Python: Trait interface implementations must now inherit from the trait base class.
  This will look like class PyTraitName(RustTraitName):

What's new?

• All user-defined types can now be renamed with the proc-macro name = "NewName" attribute (like already supported for methods and constructors) (#​2661)
• Enums and Records support exporting uniffi traits (ie, Display, Hash, Eq etc) (#​2555)
• Support for exporting the Ord trait, allowing objects to be ordered by Rust (#​2583).
• #[uniffi(default)] literals are now optional - eg, #[uniffi(default)] and #[uniffi(default = 0)] are equivalent.
  Similarly for args; #[uniffi::export(default(arg_name))].
  When no literal is specifed, named types (objects, records, etc) can be used as long as they have suitable default values.
  (#​2543).
  Custom types too (#​2603)
• Custom enum and object types can be used as error type (#​2658)
• Objects can implement external traits (#​2430)
• Fix for external errors when error only used externally (#​2641)
• Kotlin:
  • Switch to JNA direct mapping (#​2229)
  • Support throwing external error (#​2629)
  • The NoPointer placeholder object used to create fake interface instances has been renamed to NoHandle
• Python:
  • Improved how default values are handled in function signatures etc and more canonical use of Python dataclasses, all towards making mypy happier (#​2552)
  • Methods now have typing annotations for return values (#​2625)
  • Fix relative imports (#​2657)
  • Fix shadowing param names with internal variables in Python (#​2628/#​2645)
  • Don't allow objects to be passed as arguments when traits are expected (#​2649)
• Swift:
  • All object protocol conformances are public (#​2671)
  • Initialization functions now have a stable ordering when using external types.
    This makes the generated source files deterministic.

⚠️ Breaking Changes for external bindings authors ⚠️

• uniffi_bindgen::backend has been removed.
• #[uniffi(default)] changes how defaults are represented.
• FfiType::RustArcPtr has been removed and the FFI type for objects/interfaces is now a u64.
  Bindings authors will need to update their code to reflect this:
  • Lowering/lifting now uses u64 values
  • The free function inputs a u64 handle rather than a raw pointer
  • The clone function inputs and returns a u64 handle rather than a raw pointer
• Enums and Records can have methods, so the Method now carries self_type instead of the object name.
  In the templates, for Callable.takes_self() is replaced with Callable.self_type().
• Trait / Callback interface changes
  • VTable fields are now: free, clone, followed by a field for each interface method.
    Note That free is now at the start of the vtable rather than the end.
  • Trait interface changes:
    • Foreign handles must always have the lowest bit set
    • Both Rust and foreign handles can now be passed across the FFI.
      When Lifting/lowering trait interface handles, check if the handle was generated from Rust or the foreign side.
  • See https://github.com/mozilla/uniffi-rs/pulls/2586 examples of how the builtin bindings here changed.

All changes in v0.30.0.

v0.29.3

Compare Source

• Fixed a bug where objects with alignment >= 32 could be freed to early (#​2600)

All changes in v0.29.4.

v0.29.2

Compare Source

What's new?

• HashMaps in UDL now support a default value with an empty map (#​2539).

All changes in v0.29.3.

v0.29.1

Compare Source

What's fixed?

• Allow uniffi_reexport_scaffolding! macro to work in Rust 2024 (#​2476)

• Python: fix issues with unusual name capitalization, (#​2464)

• Swift bindings can now generate automatic conformance to the CaseIterable protocol for simple enums and errors using generate_case_iterable_conformance = true in the configuration.

• Swift bindings can now generate automatic conformance to the Codable protocol for records, enums and errors using generate_codable_conformance = true in the configuration. Be aware that serialization in Swift may lead to different and incompatible results compared to serialization in Rust.

All changes in v0.29.2.

⚠️ Breaking Changes for external bindings authors ⚠️

• Some async-related names have changed. Bindings authors may need to update their code to reflect
  the new names. This is a name-change only -- the FFI and semantics are still the same.

  • UniffiForeignFutureFree is now UniffiForeignFutureDroppedCallback
  • UniffiForeignFuture is UniffiForeignFutureDroppedCallbackStruct.
  • RustFuturePoll::MaybeReady is now RustFuturePoll::Wake.

v0.29.0

Compare Source

What's fixed?

• Bindings support lift and lower for CustomTypes in uniffi.toml to match the docs (#​2438)

• Python: fix using Vecs and other composite types in tuple enums (#​2445)

• Kotlin: fix interfaces in sequences and records being not disposed (#​2479)

What's changed?

• Rust 2024 edition is supported, msrv is 1.82.0

• The uniffi-bindgen CLI support no longer brings in the clap/color feature, reducing dependencies (#​2435)

• Protocols generated for Swift now conform to the Sendable protocol. This means that UniFFI traits will too, but
  it also means foreign implemented traits also must when Swift 6 conformance is enabled.
  See the Swift section of the manual for more. (#​2450)

• You can now optionally specify extra frameworks like CoreBluetooth or CoreFoundation when generating a modulemap file for an xcframework.

All changes in v0.29.1.
