Types ¶

type AtomicPtr ¶

type AtomicPtr struct {
	// contains filtered or unexported fields
}

An AtomicPtr is a pointer to a value of type Value that can be atomically loaded and stored. The zero value of an AtomicPtr represents nil.

Note that copying AtomicPtr by value performs a non-atomic read of the stored pointer, which is unsafe if Store() can be called concurrently; in this case, do `dst.Store(src.Load())` instead.

func (*AtomicPtr) Load ¶

func (p *AtomicPtr) Load() *Value

Load returns the value set by the most recent Store. It returns nil if there has been no previous call to Store.

func (*AtomicPtr) Store ¶

func (p *AtomicPtr) Store(x *Value)

Store sets the value returned by Load to x.

func (*AtomicPtr) Swap ¶

func (p *AtomicPtr) Swap(x *Value) *Value

Swap atomically stores `x` into *p and returns the previous *p value.

type Value ¶

type Value struct{}

Value is a required type parameter.
