This project has been archived. Please check out tidwall/hashmap for a fitter, happier, more productive hashmap library.

A simple and efficient hashmap package for Go using the xxhash algorithm, open addressing, and robin hood hashing.

This is an alternative to the standard Go map.

To start using rhh, install Go and run go get:

$ go get github.com/tidwall/rhh

This will retrieve the library.

The Map type works similar to a standard Go map, and includes four methods: Set, Get, Delete, Len.

var m rhh.Map
m.Set("Hello", "Dolly!")
val, _ := m.Get("Hello")
fmt.Printf("%v\n", val)
val, _ = m.Delete("Hello")
fmt.Printf("%v\n", val)
val, _ = m.Get("Hello")
fmt.Printf("%v\n", val)

// Output:
// Dolly!
// Dolly!
// <nil>
