Struct want::Giver [] [src]

pub struct Giver { /* fields omitted */ }

An entity that gives a value when wanted.


impl Giver


Poll whether the Taker has registered interest in another value.

  • If the Taker has called want(), this returns Async::Ready(()).
  • If the Taker has not called want() since last poll, this returns Async::NotReady, and parks the current task to be notified when the Taker does call want().
  • If the Taker has canceled (or dropped), this returns Closed.

After knowing that the Taker is wanting, the state can be reset by calling give.


Mark the state as idle, if the Taker currently is wanting.

Returns true if Taker was wanting, false otherwise.


Check if the Taker has called want() without parking a task.

This is safe to call outside of a futures task context, but other means of being notified is left to the user.


Check if the Taker has canceled interest without parking a task.


Converts this into a SharedGiver.
