Struct BackgroundTaskManager

Source 
pub struct BackgroundTaskManager<T: NamedEntity + 'static> { /* private fields */ }
Expand description

A background task manager that can hold and manage multiple tasks When dropped, it will abort all tasks. Graceful shutdown can be performed with graceful_shutdown

Implementations§

Source§

impl<T: NamedEntity + 'static> BackgroundTaskManager<T>

Source

pub fn loop_and_monitor<S, U: IntoTask<Task = S>>(&mut self, task: U)
where S: Task + Sized + Debug, <S as Task>::Output: Into<bool>,

Wraps the task in a cancelable loop and spawns it in the background with built-in monitoring.

If required, polling should be added before a call to this function via task.into_polling()

Source

pub fn abort_all(&mut self)

Abort all tasks by dropping their cancellation senders

Source

pub async fn graceful_shutdown(&mut self)

Graceful shutdown of all tasks

This function does not have any timeout, please use graceful_shutdown_with_timeout instead for cases where you need a timeout. The function polls tasks until they are finished with a 100ms poll interval.

Source

pub async fn graceful_shutdown_with_timeout(&mut self, timeout: Duration)

Graceful shutdown of all tasks with a timeout. All tasks will be aborted if the timeout is reached.

§Arguments
  • timeout - The timeout duration for the graceful shutdown. Since the graceful_shutdown function polls tasks until they are finished with a 100ms poll interval, the timeout should be at least 100ms for the timeout to be effective.
