An opaque handle to some task which is running in the background.
Methods
impl<T> TaskHandle<T>[src]
pub fn spawn<K>(task: K) -> TaskHandle<T> where
K: Task<Output = T> + UnwindSafe + Send + Sync + 'static,
T: Send + Sync + 'static, [src]
K: Task<Output = T> + UnwindSafe + Send + Sync + 'static,
T: Send + Sync + 'static,
Spawn a Task in the background, returning the a TaskHandle so you
can cancel it or retrieve the result later on.
pub fn poll(&self) -> Option<Result<T, Error>>[src]
Check if the background task has finished.
If the other end hangs up for whatever reason this will return an error.
pub fn wait(self) -> Result<T, Error>[src]
Block the current thread until the task has finished and returned a result.
pub fn cancel(&self)[src]
Cancel the background task.
pub fn cancelled(&self) -> bool[src]
Has this task been cancelled?
