bounded-spsc-queue | A Bounded SPSC queue for Rust

bounded-spsc-queue is a Rust library. bounded-spsc-queue has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This crate provides a very simple bounded, Single-producer Single-consumer (SPSC) queue for Rust. It provides a data structure for two threads to communicate in one direction with minimal overhead and bounded semantics. Compared to a sync_channel, this queue provides a small but consistent speedup. sync_channel utilizes an unbounded linked-list data structure under the covers, while bounded_spsc_queue is a simple ring buffer with single, solid block of allocated memory. The solid block of memory allows better cache pre-fetching due to less pointer indirection, and generally simpler operations to achieve a bounded SPSC queue.
