Bump uniffi_bindgen from 0.24.3 to 0.25.0

[dependabot]

Bumps uniffi_bindgen from 0.24.3 to 0.25.0.

Changelog

Sourced from uniffi_bindgen's changelog.

Migrating to UniFFI 0.23+

• Update your Cargo.toml file to only depend on the uniffi crate. Follow the directions from the Prerequisites section of the manual
• Create a uniffi-bindgen binary for your project. Follow the directions from the Foreign language bindings section of the manual.
• Uninstall the system-wide uniffi_bindgen: cargo uninstall uniffi_bindgen. (Not strictly necessary, but you won't be using it anymore).

[[UnreleasedUniFFIVersion]] (backend crates: [[UnreleasedBackendVersion]]) - ([[ReleaseDate]])

All changes in [[UnreleasedUniFFIVersion]].

What's new

• Proc-macros can now expose standard Rust traits (eg, Display, Eq, etc)

• Fixed issues when trying to combine UDL and procmacros in the same crate when the "namespace" is different from the crate name. This meant that the "ffi namespace" has changed to consistently be the crate name, rather than either the crate name or the namespace name depending on whether the item was declared via a procmacro or UDL. This should be invisible in most cases, but custom build environments might require some changes. Specifically:

  • uniffi::generate_scaffolding(udl_path) now uses the udl_path to locate the corresponding Cargo.toml, which is parsed to determine the crate name (ie, the name under the [lib] entry). If your environment is such that Cargo.toml can't be located or parsed, you should instead use uniffi::generate_scaffolding_for_crate(udl_path, crate_name).
  • Similarly, when executing uniffi_bindgen from the command-line to generate bindings and when not using "library mode", Cargo.toml will be located and parsed to determine the crate name. Specifying --crate-name on the command-line can be used to avoid this and use the specified value.

• Crates can now use proc-macros without UDL files to export their interface. See the "Procedural Macros: Attributes and Derives" manual section for details.

• Custom Types are now supported for proc-macros, including a very low-friction way of exposing types implementing the new-type idiom.

• Proc-macros: Added support for ByRef arguments

• Proc-macros: Implemented custom type conversion error handling (https://mozilla.github.io/uniffi-rs/udl/custom_types.html#error-handling-during-conversion)

• Error types must now implement Error + Send + Sync + 'static.

• Proc-macros: The handle_unknown_callback_error attribute is no longer needed for callback interface errors

• Foreign types can now implement trait interfaces

What's Fixed

• Updated the async functionality to correctly handle cancellation (#1669)
• Kotlin: Fixed low-level issue with exported async APIs

What's changed?

• Implementing From<uniffi::UnexpectedUniFFICallbackError is now optional for callback interface error types. If the error type implements that, things will continue to work as before. If not, then any unexpected callback error will result in a Rust panic.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
