im-rs is a Rust library providing fast immutable (persistent) collection datatypes such as vectors, hash maps, and hash sets with structural sharing. It ships in two variants: a thread-safe version (im) and a faster non-thread-safe version (im-rc).
Use cases
- use immutable data structures in Rust for cheap cloning
- implement undo/redo with persistent collections
- share state safely across threads without locks
- build functional-style Rust applications with persistent maps and vectors
- efficiently snapshot large collections without copying
When to choose
- you need cheap O(1) clones or snapshots of collections
- you want thread-safe immutable collections in Rust
- you're building editor-like or state-history-heavy applications
When to avoid
- you only need standard mutable collections with no sharing requirements
- you need absolute maximum single-threaded mutation performance
- you're not working in Rust
