mutex in a struct

tags: learning go programming

content

it’s common to see this pattern, where mutex is included in a struct with some other data:

type Container struct{
    value int
    mutex sync.Mutex
}

and later be used like:

func (c *Container) someFunc() {
    c.mutex.Lock()
    defer c.mutex.Unlock()
    // do something with c.value
}
