gompool is a simple allocation-free and lock-free memory pool library written in golang using treiber stack
- go (>= 1.8)
go get github.com/hlts2/gompool// Create 10 pools of `*bytes.Buffer`
pools := gompool.NewGompool(10, func() interface{} {
return &bytes.Buffer{}
})
pool1 := pools.Get()
pool2 := pools.Get()
buf1 := pool1.Value.(*bytes.Buffer)
buf1.WriteString("Hello world1")
buf2 := pool2.Value.(*bytes.Buffer)
buf2.WriteString("Hello world2")
pools.Put(pool1) // Return pool1 to pools
pools.Put(pool2) // Return pool2 to poolsgompool vs sync.Pool(Standard library)
