Types ¶
type Value ¶
type Value[T any] struct { // contains filtered or unexported fields }
A Value provides an atomic load and store of a value of type T. The zero value of a Value returns the zero value of T from Load. Once Store has been called, a Value must not be copied.
A Value must not be copied after first use.
func (*Value[T]) Load ¶
func (v *Value[T]) Load() T
Load returns the value set by the most recent Store. It returns the zero value of T if there has been no call to Store for this Value.
func (*Value[T]) Store ¶
func (v *Value[T]) Store(val T)
Store sets the value of the Value to val.
If T is an interface type, all calls to Store for a given Value must use non-nil values of the same concrete type. Store of an inconsistent type panics, as does Store(nil).
func (*Value[T]) Swap ¶
func (v *Value[T]) Swap(new T) (old T)
Swap stores new into the Value and returns the previous value. It returns the zero value of T if the Value is empty.
If T is an interface type, all calls to Swap for a given Value must use non-nil values of the same concrete type. Store of an inconsistent type panics, as does Store(nil).
