Rust Ring Buffers: A Deep Dive
While working on a MIDI project, the author needed a way to store recent messages without unbounded memory growth. A ring buffer proved to be the solution. This post explains ring buffers, their functionality, and use cases. It compares Rust's standard library `VecDeque` with third-party libraries like `circular-buffer` and `ringbuffer`. `VecDeque` offers flexibility but resizes dynamically; fixed-size alternatives like `circular-buffer` and `ringbuffer` avoid reallocation overhead but are less flexible. The author concludes that for fixed-size needs, third-party libraries save development time and effort.
