What a polyoxide crate needs of an async runtime: a detached spawn, a sleep, and a monotonic clock. Everything else in this crate (spawn’s Task, timeout, Interval) is built on these, so an implementor writes only these.

A client takes its runtime from its builder, and falls back to default_runtime(); nothing is process-wide.

Required Methods

fn spawn(&self, task: BoxFuture<()>)

Run task to completion, detached.

fn sleep(&self, duration: Duration) -> BoxFuture<()>

Complete after duration. Any duration, Duration::MAX included, is valid.

fn now(&self) -> Instant

The runtime’s monotonic clock.

Provided Methods

fn sleep_until(&self, deadline: Instant) -> BoxFuture<()>

Complete at deadline, at once when it has passed.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
