rpds is a Rust library providing fully persistent (immutable) data structures with structural sharing, including List, Vector, Stack, Queue, HashTrieMap, HashTrieSet, RedBlackTreeMap, and RedBlackTreeSet. It is a well-maintained crates.io package supporting no_std environments.
Use cases
- use immutable data structures in Rust
- persistent lists and vectors with structural sharing
- immutable maps and sets for functional-style code
- share data between threads without cloning
- no_std compatible data structures
- efficient copy-on-write collections
When to choose
- you need immutable/persistent collections in Rust
- you want structural sharing to avoid deep copies
- you write functional-style Rust code
- you need no_std support
When to avoid
- you need mutable in-place performance above all
- you only need standard HashMap/Vec semantics
- you work in a non-Rust language
