Trait Spawner

pub trait Spawner:
    Clone
    + Send
    + Sync
    + 'static {
    // Required method
    fn spawn<F, T>(&self, label: &str, f: F) -> Handle<T> 
       where F: Future<Output = T> + Send + 'static,
             T: Send + 'static;
}

Interface that any task scheduler must implement to spawn sub-tasks in a given root task.

Required Methods

fn spawn<F, T>(&self, label: &str, f: F) -> Handle<T>

where F: Future<Output = T> + Send + 'static, T: Send + 'static,

Enqueues a task to be executed.

Label can be used to track how many instances of a specific type of task have been spawned or are running concurrently (and is appened to all metrics). Label is automatially appended to the parent task labels (i.e. spawning “fun” from “have” will be labeled “have_fun”).

Unlike a future, a spawned task will start executing immediately (even if the caller does not await the handle).

Object Safety

This trait is not object safe.
