Struct CancellationToken 

pub struct CancellationToken(/* private fields */);

Cancellation of a single operation. Connect transport cancellation here; stopping polling alone does not stop browser Fetch or undo a server operation.

Implementations

impl CancellationToken

pub fn is_cancelled(&self) -> bool

pub fn on_cancel(&self, callback: impl FnOnce() + 'static) -> CancelRegistration

pub fn abort_signal(&self) -> Result<AbortSignal, JsValue>

A browser AbortSignal that aborts when this token is cancelled. Pass it to any Fetch; it lives as long as the token, so it also covers body reads.
