Struct CallbackHandle 

pub struct CallbackHandle { /* private fields */ }

Cheap, clonable submission side of a CallbackPool — the seam route for RTEMS synchronous-tail hand-offs (increment W3a, decision A2). Holds only Arcs to the bands, so cloning is free and it can be handed to the delayed timer, scanOnce worker, and future engine wiring.

Implementations

impl CallbackHandle

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

Enqueue cb on priority — port of callbackRequest (callback.c:341). Returns immediately; a band worker runs the callback later. Err on a full ring (see CallbackError).

pub fn overflow_count(&self, priority: CallbackPriority) -> u64

Lifetime overflow count for a band — C queueOverflows (callback.c:57).

Trait Implementations

impl Clone for CallbackHandle

fn clone(&self) -> CallbackHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.
