Package drpcsignal holds a helper type to signal errors.
Usage
type Signal
type Signal struct {
}
Signal contains an error value that can be set one and exports a number of ways to inspect it.
func (*Signal) Err
func (s *Signal) Err() error
Err returns the error stored in the signal. Since one can store a nil error care must be taken. A non-nil error returned from this method means that the Signal has been set, but the inverse is not true.
func (*Signal) Get
func (s *Signal) Get() (error, bool)
Get returns the error set with the signal and a boolean indicating if the result is valid.
func (*Signal) IsSet
func (s *Signal) IsSet() bool
IsSet returns true if the Signal is set.
func (*Signal) Set
func (s *Signal) Set(err error) (ok bool)
Set stores the error in the signal. It only keeps track of the first error set, and returns true if it was the first error set.
func (*Signal) Signal
func (s *Signal) Signal() chan struct{}
Signal returns a channel that will be closed when the signal is set.
