Types

type Value

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

Value implements a future/promise for an arbitrary value.

func Immediate

func Immediate(value interface{}) *Value

Immediate returns a Value which resolves to 'value'.

func NewValue

func NewValue(f func() interface{}) *Value

NewValue returns a new Value future, whose value is computed by f(). f() is called concurrently - NewValue doesn't block.

func (*Value) Get

func (f *Value) Get() interface{}

Get returns the value computed by the function given to NewValue. It blocks until the value is ready.
