Types

type Resp

type Resp chan error

Resp is a channel to be used for boolean responses. A nil represents an ACK, and a non-nil represents a NACK (false). This also lets us use custom errors.

func NewResp

func NewResp() Resp

NewResp is just a helper to return the right type of response channel.

func (Resp) ACK

func (resp Resp) ACK()

ACK sends a true value to resp.

func (Resp) ACKNACK

func (resp Resp) ACKNACK(err error)

ACKNACK sends a custom ACK or NACK. The ACK value is always nil, the NACK can be any non-nil error value.

func (Resp) ACKWait

func (resp Resp) ACKWait()

ACKWait waits for a +ive Ack from a Resp channel.

func (Resp) NACK

func (resp Resp) NACK()

NACK sends a false value to resp.

func (Resp) Wait

func (resp Resp) Wait() error

Wait waits for any response from a Resp channel and returns it.
