Struct Runtime 

pub struct Runtime { /* private fields */ }

The main runtime instance, holds all global state and thread-specific handles are created by it.

Implementations

impl Runtime

pub fn new(background_threads: usize) -> Self

Creates a new runtime with a fixed number of background threads.

Background threads execute tasks that are spawned in the background, allowing foreground threads to keep doing other work.

pub fn handle(&self) -> Handle

pub fn spawn<F>(&self, future: F) -> JoinHandle<F::Output>

where F: Future + Send + 'static, F::Output: Send + Sync,

Spawn a future to run in the background. The future can make progress by any participating thread.

If the runtime doesn’t have any background threads, the JoinHandle should be polled/awaited explicitly.

pub fn block_on<F>(&self, future: F) -> F::Output

where F: Future + Send + 'static, F::Output: Send + Sync,

Run a future, blocking the current thread until its done.

The future might end up running on a different thread, and this thread might make progress on other futures before returning.
