Struct BackgroundHandle 

pub struct BackgroundHandle { /* private fields */ }

Cheap, clonable submission side of a BackgroundExecutor. Every method enqueues and returns immediately; the work runs on a background thread.

This is the type the sans-io seam routes RTEMS tail hand-offs into — the runtime-free counterpart of crate::runtime::task::spawn.

Implementations

impl BackgroundHandle

pub fn callback( &self, priority: CallbackPriority, cb: Callback, ) -> Result<(), CallbackError>

Enqueue an immediate callback on priority — C callbackRequest (callback.c:341).

pub fn callback_delayed( &self, delay: Duration, priority: CallbackPriority, cb: Callback, )

Enqueue a callback to run after delay on priority — C callbackRequestDelayed (callback.c:410).

pub fn scan_once(&self, cb: OnceCallback) -> Result<(), ScanOnceOverflow>

Enqueue a one-shot record-process tail — C scanOnce (dbScan.c:664).

pub fn callbacks(&self) -> &CallbackHandle

The callback-submission handle alone.

pub fn timer(&self) -> &TimerHandle

The delayed-timer handle alone.

pub fn scan_once_handle(&self) -> &ScanOnceHandle

The scanOnce-submission handle alone.

Trait Implementations

impl Clone for BackgroundHandle

fn clone(&self) -> BackgroundHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.
