[−][src]Struct kas::Future
A future value, pending UI operation
This is a simpler form of future than the std::future::Future trait,
relying on the UI event system for execution. It also does not come with a
waker; since calling into widget code is only possible through the event
system, an UpdateHandle should be used to wake the recipient.
Implementations
impl<T: 'static> Future<T>[src]
pub fn new_box_fnmut<U: 'static>(
f: Box<dyn FnMut(&mut U) -> T>
) -> (Self, Box<dyn FnMut(&mut U)>)[src]
f: Box<dyn FnMut(&mut U) -> T>
) -> (Self, Box<dyn FnMut(&mut U)>)
Construct, given a boxed closure to produce the final value
Returns the future and a finish closure to set the value when done.
pub fn is_finished(&self) -> bool[src]
Check whether this is finished
pub fn try_finish(self) -> Result<T, Self>[src]
Returns a result on completion
It may be worth checking Future::is_finished before calling this method.
