BackgroundExecutor

Struct BackgroundExecutor 

Source
pub struct BackgroundExecutor { /* private fields */ }
Expand description

Owns the three background facilities (callback pool, delayed timer, scanOnce worker) and every thread backing them. Constructing it starts the threads; dropping it stops and joins them.

The delayed timer fires its due callbacks into the callback pool, exactly as C’s notify routes an expired epicsTimer back through callbackRequest (callback.c:404-419).

Implementations§

Source§

impl BackgroundExecutor

Source

pub fn new() -> Self

Start all three facilities with their C-default sizing.

Source

pub fn handle(&self) -> BackgroundHandle

A cheap, clonable handle over all three facilities — the seam route for RTEMS synchronous-tail hand-offs.

Source

pub fn callbacks(&self) -> &CallbackPool

The callback executor pool.

Source

pub fn timer(&self) -> &DelayedTimer

The delayed-callback timer.

Source

pub fn scan_once(&self) -> &ScanOnceQueue

The scanOnce facility.
