Trait flutter_rust_bridge::handler::Executor

pub trait Executor: RefUnwindSafe {
    fn execute<TaskFn, TaskRet>(&self, wrap_info: WrapInfo, task: TaskFn)
    where
        TaskFn: FnOnce(TaskCallback) -> Result<TaskRet> + Send + UnwindSafe + 'static,
        TaskRet: IntoDart;
    fn execute_sync<SyncTaskFn>(
        &self,
        wrap_info: WrapInfo,
        sync_task: SyncTaskFn
    ) -> Result<SyncReturn<Vec<u8>>>
    where
        SyncTaskFn: FnOnce() -> Result<SyncReturn<Vec<u8>>> + UnwindSafe;
}

An executor model for Rust functions.

For example, the default model is ThreadPoolExecutor which runs each function in a separate thread.

Required Methods

fn execute<TaskFn, TaskRet>(&self, wrap_info: WrapInfo, task: TaskFn) where
    TaskFn: FnOnce(TaskCallback) -> Result<TaskRet> + Send + UnwindSafe + 'static,
    TaskRet: IntoDart, 

Executes a Rust function and transforms its return value into a Dart-compatible value, i.e. types that implement IntoDart.

fn execute_sync<SyncTaskFn>(
    &self,
    wrap_info: WrapInfo,
    sync_task: SyncTaskFn
) -> Result<SyncReturn<Vec<u8>>> where
    SyncTaskFn: FnOnce() -> Result<SyncReturn<Vec<u8>>> + UnwindSafe, 

Executes a Rust function that returns a SyncReturn.
