Struct CurrentDispatcher 

Source 
pub struct CurrentDispatcher;
Expand description

A placeholder for the currently active dispatcher.

Trait Implementations§

Source§

impl Clone for CurrentDispatcher

Source§

fn clone(&self) -> CurrentDispatcher

Returns a duplicate of the value. Read more
1.0.0 (const: unstable) · Source§

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

Performs copy-assignment from source. Read more
Source§

impl Debug for CurrentDispatcher

Source§

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

Formats the value using the given formatter. Read more
Source§

impl Default for CurrentDispatcher

Source§

fn default() -> CurrentDispatcher

Returns the “default value” for a type. Read more
Source§

impl GetAsyncDispatcher for CurrentDispatcher

Source§

fn try_get_async_dispatcher(&self) -> Option<AsyncDispatcher>

Returns a refcounted handle to the active dispatcher for this object, if there is one. Some types of dispatchers (like for the current dispatcher of a thread) may not always have an active dispatcher, so it is returned as an option.
Source§

fn get_async_dispatcher(&self) -> AsyncDispatcher

Returns a refcounted handle to the active dispatcher for this object. Read more
Source§

impl OnDriverDispatcher for CurrentDispatcher

Source§

fn spawn_local( &self, future: impl Future<Output = ()> + 'static, ) -> JoinHandle<()>
where Self: 'static,

Spawn an asynchronous local task on this dispatcher. If this returns Ok then the task has successfully been scheduled and will run or be cancelled and dropped when the dispatcher shuts down. The returned future’s result will be Ok if the future completed successfully, or an Err if the task did not complete for some reason (like the dispatcher shut down). Read more
Source§

fn compute_local<T: Send + 'static>( &self, future: impl Future<Output = T> + 'static, ) -> Task<T>
where Self: 'static,

Spawn a local asynchronous task that outputs type ‘T’ on this dispatcher. The returned future’s result will be Ok if the task was started and completed successfully, or an Err if the task couldn’t be started or failed to complete (for example because the dispatcher was shutting down). Read more
Source§

impl PartialEq for CurrentDispatcher

Source§

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

Tests for self and other values to be equal, and is used by ==.
1.0.0 (const: unstable) · Source§

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

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

Mutably borrows from an owned value. Read more
Source§

impl<T> CloneToUninit for T
where T: Clone,

Source§

unsafe fn clone_to_uninit(&self, dest: *mut u8)

🔬This is a nightly-only experimental API. (clone_to_uninit)
Performs copy-assignment from self to dest. Read more
Source§

impl<T> From<T> for T

Source§

fn from(t: T) -> T

Returns the argument unchanged.

Source§

impl<T, U> Into<U> for T
where U: From<T>,

Source§

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Source§

impl<D> OnDispatcher for D
where D: GetAsyncDispatcher + Clone + Send + Sync,

Source§

fn on_dispatcher<R>( &self, f: impl FnOnce(Option<AsyncDispatcherRef<'_>>) -> R, ) -> R

Runs the function f with a lifetime-bound AsyncDispatcherRef for this object’s dispatcher. If the dispatcher is no longer valid, the callback will be given None. Read more
Source§

fn on_maybe_dispatcher<R, E>( &self, f: impl FnOnce(AsyncDispatcherRef<'_>) -> Result<R, E>, ) -> Result<R, E>
where E: From<Status>,

Helper version of OnDispatcher::on_dispatcher that translates an invalidated dispatcher handle into a [Status::BAD_STATE] error instead of giving the callback None. Read more
Source§

fn spawn( &self, future: impl Future<Output = ()> + Send + 'static, ) -> JoinHandle<()>
where D: 'static,

Spawn an asynchronous task on this dispatcher. If this returns Ok then the task has successfully been scheduled and will run or be cancelled and dropped when the dispatcher shuts down. The returned future’s result will be Ok if the future completed successfully, or an Err if the task did not complete for some reason (like the dispatcher shut down). Read more
Source§

fn compute<T>( &self, future: impl Future<Output = T> + Send + 'static, ) -> Task<T>
where T: Send + 'static, D: 'static,
