Module criterion::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.

Structs

• AsyncStdExecutorasync_std
  Runs futures on the ‘async-std’ crate’s global executor
• FuturesExecutorasync_futures
  Runs futures on the ‘futures’ crate’s built-in current-thread executor
• SmolExecutorasync_smol
  Runs futures on the ‘smol’ crate’s global executor

Traits

• AsyncExecutor
  Plugin trait used to allow benchmarking on multiple different async runtimes.
