strider
[ringbuffer operations on multiple values at once] (https://snd.github.io/strider/strider/trait.SliceRing.html) with an [efficient implementation] (https://snd.github.io/strider/strider/index.html#performance). written in rust.
useful for moving a window with variable step through a possibly infinite stream of values [while avoiding unnecessary memory allocations] (https://snd.github.io/strider/strider/index.html#memory)
handy when computing the short-time fourier transform.
to use add strider = "*"
to the [dependencies] section of your Cargo.toml and call extern crate strider; in your code.
