go-radix Build Status

Provides the radix package that implements a radix tree. The package only provides a single Tree implementation, optimized for sparse nodes.

As a radix tree, it provides the following: * O(k) operations. In many cases, this can be faster than a hash table since the hash function is an O(k) operation, and hash tables have very poor cache locality. * Minimum / Maximum value lookups * Ordered iteration

For an immutable variant, see go-immutable-radix.

Documentation

The full documentation is available on Godoc.

Example

Below is a simple example of usage

// Create a tree
r := radix.New()
r.Insert("foo", 1)
r.Insert("bar", 2)
r.Insert("foobar", 2)

// Find the longest prefix match
m, _, _ := r.LongestPrefix("foozip")
if m != "foo" {
    panic("should be foo")
}
