Struct GlobalExecutor

pub struct GlobalExecutor;

Executor that switch between TokioExecutor, ThreadpoolExecutor and WasmExecutor at compile time.

• If the target is non-wasm32 and “tokio” feature is enabled, tokio would be used.
• if the target is non-wasm32 and “threadpool” feature is enabled with tokio feature disabled, futures ThreadPool will be used.
• If the target is wasm32, [wasm-bindgen-futures] would be used.

Trait Implementations

impl Clone for GlobalExecutor

fn clone(&self) -> GlobalExecutor

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GlobalExecutor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Executor for GlobalExecutor

fn spawn<F>(&self, future: F) -> JoinHandle<F::Output>

where F: Future + Send + 'static, F::Output: Send + 'static,

Spawns a new asynchronous task in the background, returning an Future JoinHandle for it.

fn spawn_abortable<F>(&self, future: F) -> AbortableJoinHandle<F::Output>

where F: Future + Send + 'static, F::Output: Send + 'static,

Spawns a new asynchronous task in the background, returning an abortable handle that will cancel the task once the handle is dropped.

fn dispatch<F>(&self, future: F)

where F: Future + Send + 'static, F::Output: Send + 'static,

Spawns a new asynchronous task in the background without an handle. Basically the same as Executor::spawn.

fn spawn_coroutine<T, F, Fut>(&self, f: F) -> CommunicationTask<T>

where F: FnMut(Receiver<T>) -> Fut, Fut: Future<Output = ()> + Send + 'static,

Spawns a new asynchronous task that accepts messages to the task using channels. This function returns an handle that allows sending a message or if there is no reference to the handle at all (in other words, all handles are dropped), the task would be aborted.

fn spawn_coroutine_with_context<T, F, C, Fut>( &self, context: C, f: F, ) -> CommunicationTask<T>

where F: FnMut(C, Receiver<T>) -> Fut, Fut: Future<Output = ()> + Send + 'static,

Spawns a new asynchronous task with provided context, that accepts messages to the task using channels. This function returns an handle that allows sending a message or if there is no reference to the handle at all (in other words, all handles are dropped), the task would be aborted.

fn spawn_unbounded_coroutine<T, F, Fut>( &self, f: F, ) -> UnboundedCommunicationTask<T>

where F: FnMut(UnboundedReceiver<T>) -> Fut, Fut: Future<Output = ()> + Send + 'static,

Spawns a new asynchronous task that accepts messages to the task using channels. This function returns an handle that allows sending a message or if there is no reference to the handle at all (in other words, all handles are dropped), the task would be aborted.

fn spawn_unbounded_coroutine_with_context<T, F, C, Fut>( &self, context: C, f: F, ) -> UnboundedCommunicationTask<T>

where F: FnMut(C, UnboundedReceiver<T>) -> Fut, Fut: Future<Output = ()> + Send + 'static,

Spawns a new asynchronous task with provided context, that accepts messages to the task using channels. This function returns an handle that allows sending a message or if there is no reference to the handle at all (in other words, all handles are dropped), the task would be aborted.

impl PartialEq for GlobalExecutor

fn eq(&self, other: &GlobalExecutor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for GlobalExecutor

fn partial_cmp(&self, other: &GlobalExecutor) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
