Types

type Value

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

func (*Value) CompareAndSwap

func (v *Value) CompareAndSwap(old, new any) (swapped bool)

CompareAndSwap executes the compare-and-swap operation for the Value.

All calls to CompareAndSwap for a given Value must use values of the same concrete type. CompareAndSwap of an inconsistent type panics, as does CompareAndSwap(old, nil).

func (*Value) Load

func (v *Value) Load() (val any)

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

func (*Value) Store

func (v *Value) Store(val any)

Store sets the value of the Value v to val. All calls to Store for a given Value must use values of the same concrete type. Store of an inconsistent type panics, as does Store(nil).

func (*Value) Swap

func (v *Value) Swap(new any) (old any)

Swap stores new into Value and returns the previous value. It returns nil if the Value is empty.

All calls to Swap for a given Value must use values of the same concrete type. Swap of an inconsistent type panics, as does Swap(nil).
