triecache是一个内存中的 key - value 缓存，用法类似redis，对于一些想要临时存储一些数据，但是没必要接入redis的场景适用；原理是通过树形结构实现的，相较于根据map[string]interface{} 的 go-cache 等，实现了 redis 中 keys的功能
go get -u github.com/lzy1102/triecache
package main
import (
"fmt"
"github.com/lzy1102/triecache"
"time"
)
func main() {
key := "hellofdafas123"
key2 := "helloerqwr456"
value := 10
var c triecache.Cache
c = triecache.New(time.Minute*5, time.Second*10)
err := c.Set(key, value, time.Second*10)
if err != nil {
panic(err)
}
c.Set(key2, value, time.Second)
time.Sleep(time.Second * 2)
get, err := c.Get(key)
if err != nil {
fmt.Println(err)
}
fmt.Println("key ", key, " value ", get)
get, err = c.Get(key2)
if err != nil {
fmt.Println(err)
}
fmt.Println("key2 ", key2, " value2 ", get)
keys, err := c.Keys("hello*")
if err != nil {
fmt.Println(err)
}
fmt.Println("keys ", keys)
for _, s := range keys {
v, _ := c.Get(s)
fmt.Println(s, v)
}
}
