# gpin
A [spinlock](https://en.wikipedia.org/wiki/Spinlock) implementation for Go.
## Requirement
Go 1.17
## Installation
```shell
go get github.com/hlts2/gpin
```
## Example
```go
package main
import (
"fmt"
"time"
"github.com/hlts2/gpin"
)
type Counter struct {
l gpin.Spinlock
v map[string]int
}
func (c *Counter) Increment(key string) {
c.l.Lock()
c.v[key]++
c.l.Unlock()
}
func (c *Counter) Get(key string) int {
c.l.Lock()
defer c.l.Unlock()
return c.v[key]
}
func main() {
c := Counter{
v: make(map[string]int),
}
for i := 0; i < 100; i++ {
go c.Increment("example")
}
time.Sleep(time.Second)
fmt.Println(c.Get("example")) // 100
}
```
