Crate flutter_rust_bridge

Main documentation is in https://github.com/fzyzcjy/flutter_rust_bridge

Modules

• handler

Macros

• opaque_dyn
  Macro helper to instantiate an RustOpaque<dyn Trait>, as Rust does not support custom DSTs on stable.
• transfer
  On WASM, JsValues cannot be shared between scopes but instead can be “transferred”. Rust however is not aware of transferables and therefore cannot capture these values. This macro wraps a closure and returns a TransferClosure on WASM platforms which will capture these special values, or a normal FnOnce on other platforms. Note that the parameter names must match available variables/bindings from the outer scope.

Structs

• CatchUnwindWithBacktrace
  Similar to the output of catch_unwind, but with extra backtrace
• Dart2RustMessageSse
• DartOpaque
  Arbitrary Dart object, whose type can be even non-encodable and non-transferable.
• JoinHandle
  An owned permission to join on a task (await its termination).
• PanicBacktrace
  Utility for tracking panic backtrace.
• Rust2DartSendError
  Error when sending message from rust to dart
• SimpleAsyncRuntime
• SimpleThreadPool
• SseCodec
  Codec that does a simple serialization
• ZeroCopyBuffer
  Wrapping a Vec in this tuple struct will allow into_dart() to send it as a DartNativeExternalTypedData buffer with no copy overhead

Traits

• BaseAsyncRuntime
• BaseCodec
• BaseThreadPool
• DartSafeDeprecated
• Handler
  Provide your own handler to customize how to execute your function calls, etc.
• IntoDart
  A trait to convert between Rust types and Dart Types that could then be sent to the isolate
• IntoIntoDart
  Basically the Into trait. We need this separate trait because we need to implement it for Vec etc. These blanket implementations allow us to accept external types in various places. The initial reason for this was to allow mirrored types in StreamSink<>. See also PR 1285
• Rust2DartMessageTrait
  An encoded message

Functions

• setup_default_user_utils
  Setup defaults that is usually useful for a new project. Surely, you are free to customize everything.
• spawn
  Spawns a new asynchronous task, returning a JoinHandle for it.
• spawn_blocking_with
  Similar to tokio’s spawn_blocking, except that you need to provide a second argumnet. If you are using flutter_rust_bridge, the second argument can be easily provided: Just use FLUTTER_RUST_BRIDGE_HANDLER.thread_pool().
• spawn_local
  Spawns a !Send future on the current LocalSet.

Type Aliases

• DartAbi
• DartDynamic
  Use this type to represent Dart dynamic values
• DartFnFuture
  Roughly speaking, just BoxFuture + UnwindSafe.
• DefaultHandler
  The default handler used by the generated code.
• RustAutoOpaqueNom
  Please refer to RustAutoOpaque for doc.
• RustOpaqueNom
  Please refer to RustOpaque for doc.

Attribute Macros

• frb
  Attribute to guide code generation.
