Module async_executor

This module defines a trait that can be used to plug in different Futures executors into Criterion.rs’ async benchmarking support.

Implementations are provided for:

• Tokio (implemented directly for tokio::Runtime)
• Async-std
• Smol
• The Futures crate

Please note that async benchmarks will have a small amount of measurement overhead relative to synchronous benchmarks. It is recommended to use synchronous benchmarks where possible, to improve measurement accuracy.
