an rope

A rope is an efficient data structure for large mutable strings. It's essentially a binary tree whose leaves are strings.

Our Rope implementation aims to eventually function as a superset of Rust's String, providing the same API plus additional methods. Therefore, code which uses String can easily be ported to use Rope.

Rope provides two APIs for editing a Rope: a destructive, edit-in-place API whose methods match those of String, and a non-destructive, persistant API.

compatibility

an-rope is built against the latest stable, beta, and nightly Rust releases, on macOS and Ubuntu. Some features rely on nightly Rust, and may not be available on other release channels.

cargo feature flags

• tendril: use the tendril library to optimise performance for small strings.
• rebalance: enable Rope rebalancing.
• unstable: enable nightly Rust features. pass this flag if building on nightly Rust.
