A collection of generic data structures for Go 1.18+ built with type parameters, including trees, maps, sets, heaps, queues, ropes, and tries. Each structure lives in its own subpackage with documentation and examples.

Use cases

• use generic data structures in Go without writing my own
• need an AVL tree or B-tree with type parameters
• want an LRU cache implementation in Go
• need a bidirectional map or multimap
• looking for a rope or interval tree in Go
• need a hashmap that can be efficiently copied

When to choose

• you need common data structures with Go generics and minimal dependencies
• you want small, focused subpackages you can import individually
• you need structures like ropes, interval trees, or copy-on-write hashmaps not in the standard library

When to avoid

• you need concurrent/thread-safe data structures out of the box
• you need a batteries-included collections library with iterators and rich APIs
• you are not using Go 1.18 or later
