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!

Whisk targets Rust 1.64 and later.

Benchmarks for v0.8.0 actor on pasts runtime (compared to dynamic library):

Dynamic library: 6ns
Whisk (2-thread): 4.029µs
Flume (2-thread): 4.172µs
Whisk (1-thread): 145ns
Flume (1-thread): 247ns

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.
