Raw Blame History

`rhh` (Robin Hood Hashmap)

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.

Getting Started

Installing

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

$ go get -u github.com/tidwall/rhh

This will retrieve the library.

Usage

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>
