• A BlockingPermit for limiting the number of concurrent blocking operations via a Semaphore type.

• A Cleaver for splitting Stream buffers into more manageable sizes.

• A YieldStream for yielding between Stream items.

MSRV := 1.45.2

The crate will fail fast on any lower rustc (via a build.rs version check) and is also CI tested on this version.
