|
|
=========
|
||
|
|
|
||
|
|
Provides the `radix` package that implements a [radix tree](http://en.wikipedia.org/wiki/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](https://github.com/hashicorp/go-immutable-radix).

Example
|
||
|
|
=======
|
||
|
|
|
||
|
|
Below is a simple example of usage
|
||
|
|
|
||
|
|
```go
|
||
|
|
// 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")
|
||
|
|
}
|
||
|
|
```
