Module features 

Opt-in feature catalog. Each submodule is gated by its own Cargo feature flag and adds a specific capability to the base MPSC queue without bloating the core build.

See Cargo.toml [features] for the catalog + the README’s “Features” section for per-feature p99 numbers and use cases.

Bounded MPSC queue: fixed-capacity ring buffer with backpressure.
