}Expand description
A receiver or a sender that can participate in select.
This is a handle that assists select in executing an operation, registration, deciding on the appropriate deadline for blocking, etc.
Required Methods§
sourcefn try_select(&self, token: &mut Token) -> bool
fn try_select(&self, token: &mut Token) -> bool
Attempts to select an operation and returns true on success.
sourcefn register(&self, oper: Operation, cx: &Context) -> bool
fn register(&self, oper: Operation, cx: &Context) -> bool
Registers an operation for execution and returns true if it is now ready.
sourcefn unregister(&self, oper: Operation)
fn unregister(&self, oper: Operation)
Unregisters an operation for execution.
sourcefn accept(&self, token: &mut Token, cx: &Context) -> bool
fn accept(&self, token: &mut Token, cx: &Context) -> bool
Attempts to select an operation the thread got woken up for and returns true on success.
