Usage
Cache
package main
import (
"fmt"
"time"
"github.com/xuender/toolkit"
)
func main() {
// LRU
cache := toolkit.NewCache(time.Second*3, true)
cache.Set("key1", "value1")
cache.SetByDuration("key2", "value2", time.Second)
cache.Set("key3", "value3")
fmt.Println("init size:", cache.Size())
time.Sleep(time.Second * 2)
cache.Get("key3") // reset expire time.
fmt.Println("2 Second:", cache.Size())
time.Sleep(time.Second * 2)
fmt.Println("4 Second:", cache.Size())
}
SyncMap
package main
import (
"fmt"
"github.com/xuender/toolkit"
)
func main() {
m := toolkit.NewSyncMap()
m.Set("key1", "value1")
m.Set("key2", "value2")
fmt.Println(m.Get("key1"))
fmt.Println(m.Size())
}
ChMap
package main
import (
"fmt"
"github.com/xuender/toolkit"
)
func main() {
m:= toolkit.NewChMap()
defer m.Close()
m.Set("key1", "value1")
m.Set("key2", "value2")
fmt.Println(m.Get("key1"))
fmt.Println(m.Size())
}

Types ¶
type Cache ¶
type Cache struct {
Expire time.Duration
LRU bool
Callback func(key, value interface{})
// contains filtered or unexported fields
}
Cache support LRU (Least Recently Used).
Example ¶
cache := NewCache(3*time.Second, true)
cache.Set("key1", "value1")
cache.SetByDuration("key2", "value2", time.Second)
cache.Set("key3", "value3")
fmt.Println(cache.Get("key1"))
fmt.Println("init size:", cache.Size())
time.Sleep(2 * time.Second)
fmt.Println(cache.Get("key3")) // reset expire time.
fmt.Println("2 second:", cache.Size())
time.Sleep(2 * time.Second)
fmt.Println("4 second:", cache.Size())
Output: value1 true init size: 3 value3 true 2 second: 2 4 second: 1
func NewCallbackCache ¶ added in v0.0.4
func NewCallbackCache(expire time.Duration, callback func(key, value interface{}), LRU ...bool) *Cache
NewCallbackCache new have del callback cache.
Example ¶
cache := NewCallbackCache(3*time.Second, func(key, value interface{}) {
fmt.Println("del:", key, value)
}, true)
cache.Set("key1", "value1")
cache.SetByDuration("key2", "value2", time.Second)
cache.Set("key3", "value3")
fmt.Println(cache.Get("key1"))
fmt.Println("init size:", cache.Size())
time.Sleep(2 * time.Second)
fmt.Println(cache.Get("key3")) // reset expire time.
fmt.Println("2 second:", cache.Size())
time.Sleep(2 * time.Second)
fmt.Println("4 second:", cache.Size())
Output: value1 true init size: 3 del: key2 value2 value3 true 2 second: 2 del: key1 value1 4 second: 1
func (*Cache) SetByDuration ¶
SetByDuration value by key.
type ChMap ¶
type ChMap struct {
// contains filtered or unexported fields
}
ChMap is channel map.
Example ¶
chMap := NewChMap()
defer chMap.Close()
chMap.Set("key1", "value1")
chMap.Set("key2", "value2")
fmt.Println(chMap.Get("key1"))
fmt.Println(chMap.Size())
Output: value1 true 2
type NumHash ¶ added in v0.0.4
NumHash is hash to num.
func NewNumHash ¶ added in v0.0.4
NewNumHash by max num.
Example ¶
h := NewNumHash(10)
for i := 0; i < 10; i++ {
h.Reset()
h.Write([]byte(fmt.Sprintf("value:%d", i)))
fmt.Println(h.Sum1(), h.Sum2(), h.Sum3(), h.Sum4())
}
Output: 3 2 0 3 4 5 4 7 5 2 7 7 6 5 1 1 7 2 4 7 8 5 8 1 3 8 6 9 4 5 9 5 5 8 3 9 6 5 6 9
