Implementations§

source§

impl BoundedExecutor

source

pub fn new(capacity: usize, executor: Handle) -> Self

Create a new BoundedExecutor from an existing tokio [Handle] with a maximum concurrent task capacity of capacity.

source

pub async fn spawn<F>(&self, f: F) -> JoinHandle<F::Output>where F: Future + Send + 'static, F::Output: Send + 'static,

Spawn a Future on the BoundedExecutor. This function is async and will block if the executor is at capacity until one of the other spawned futures completes. This function returns a [JoinHandle] that the caller can .await on for the results of the Future.

source

pub fn try_spawn<F>(&self, f: F) -> Result<JoinHandle<F::Output>, F>where F: Future + Send + 'static, F::Output: Send + 'static,

Try to spawn a Future on the BoundedExecutor. If the BoundedExecutor is at capacity, this will return an Err(F), passing back the future the caller attempted to spawn. Otherwise, this will spawn the future on the executor and send back a [JoinHandle] that the caller can .await on for the results of the Future.
