Key-value cache:

package main

import (

    "github.com/maemual/go-cache"
)

func main() {
    c := cache.New(0, 0)
    c.Set("1", 1111, 0)
    val, found := c.Get("1")
    if found {
        fmt.Println(val)
    }
    c.Increment("1", 1)
    val, found = c.Get("1")
    if found {
        fmt.Println(val)
    }
}

LRU Cache:

package main

import (
    "fmt"

    "github.com/maemual/go-cache"
)

func main() {
    lru, err := cache.NewLRU(3)
    if err != nil {
        fmt.Println(err)
    }
    lru.Add("1", 1111)
    lru.Add("2", 2222)
    lru.Add("3", 3333)
    lru.Add("4", 4444)
    _, hit := lru.Get("1")
    if hit {
        fmt.Println("Hit key 1")
    } else {
        fmt.Println("Not hit key 1")
    }
