test_executors

This crate provides extremely simple, yet useful, async executors. They are primarily useful for writing unit tests without bringing in a full-blown executor such as tokio.

The executors are:

• spin_on: polls a future in a busyloop on the current thread.
• sleep_on: polls a future on the current thread, sleeping between polls.
• spawn_on: spawns a future on a new thread, polling it there.

some_executor

This crate implements the some_executor trait for all executors, allowing them to be used in executor-agnostic code.

lib.rs:

A simple runtime that is useful for testing.

It blocks the current thread until the future completes.

Blocks the calling thread until a future is ready.
