Struct Emitter 

pub struct Emitter<T> { /* private fields */ }

The worker’s handle to a spawn_stream, for posting items back to the UI thread. Send and cloneable, so the work can hand it to nested helpers or a callback-driven library.

Implementations

impl<T: Send + 'static> Emitter<T>

pub fn emit(&self, item: T)

Posts one item and wakes the UI loop. A no-op once the stream is cancelled.

pub fn is_cancelled(&self) -> bool

Whether the Task was cancelled. A long-running worker should poll this and return — nothing else can stop it, and everything it emits from here on is discarded.

Trait Implementations

impl<T> Clone for Emitter<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
