A circular buffer for strings and traits for in-place string transforms.
This crate provides two key types: the CharCircle struct and the StringTransform trait. The CharCircle is a circular buffer specialized for UTF-8 strings, and the StringTransform trait builds upon it to provide a character-oriented API for in-place string transformations. In short, StringTransform allows you to implement transformations as iterator adaptors, with copy-on-write optimizations in mind.
Char-circle is a pure Rust library. To use it, simply add it to your Cargo.toml:
[dependencies]
char-circle = "0.1.0"
