Functions ¶

func NewChan ¶

func NewChan(ctx context.Context) (resolve, reject Resolver, promise Chan)

NewChan creates a new Chan

Types ¶

type Chan ¶

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

Chan is a Go channel-based promise

func (Chan) Await ¶

func (c Chan) Await() (interface{}, error)

Await implements Promise

func (Chan) Catch ¶

func (c Chan) Catch(fn func(rejectedReason interface{}) interface{}) Promise

Catch implements Promise

func (Chan) Then ¶

func (c Chan) Then(fn func(value interface{}) interface{}) Promise

Then implements Promise

type Promise ¶

type Promise interface {
	Then(fn func(value interface{}) interface{}) Promise
	Catch(fn func(value interface{}) interface{}) Promise
	Await() (interface{}, error)
}

Promise is a JS-like promise interface. Enables alternative implementations, like Go channels.

type Resolver ¶

type Resolver func(interface{})

Resolver can be returned from a new Promise constructor, great for resolving successes and failures with values.
