Struct i_slint_core::future::JoinHandle

source · 
pub struct JoinHandle<T>(/* private fields */);
Expand description

The return value of the spawn_local() function

Can be used to abort the future, or to get the value from a different thread with .await

This trait implements future. Polling it after it finished or aborted may result in a panic.

Implementations§

source§

impl<T> JoinHandle<T>

source

pub fn abort(self)

If the future hasn’t completed yet, this will make the event loop stop polling the corresponding future and it will be dropped

Once this handle has been aborted, it can no longer be polled
