Struct want::SharedGiver

source · [−]

pub struct SharedGiver { /* private fields */ }

Expand description

A cloneable Giver.

It differs from Giver in that you cannot poll for want. It’s only usable as a cancellation watcher.

Implementations

source

impl SharedGiver

source

pub fn is_wanting(&self) -> bool

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.

source

pub fn is_canceled(&self) -> bool

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