Whisk

Simple and fast async channels

Simple and fast async channels that can be used to implement futures, streams, notifiers, and actors. Whisk is purposely kept small, implemented in under 300 lines of Rust code, with zero dependencies (not including feature flags to enable implementation of traits from other crates) - and also works on no_std!

MSRV

Whisk targets Rust 1.60.0 and later.

Benchmarks

Benchmarks for v0.5.0 actor on pasts runtime (compared to dynamic library):

Dynamic library: 6ns
Whisk (2-thread): 6.574µs
Flume (2-thread): 7.463µs
Whisk (1-thread): 179ns
Flume (1-thread): 268ns

These aren't very well done benchmarks, but in my testing whisk is always faster on single threaded and sometimes faster on the multi-threaded benchmark.
