type StdinReader

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

Reading directly from STDIN when executing multiple processes creates issues, as STDIN read is blocking and you can't cancel it. Instead, this is the only place we read from STDIN, and we direct the byte stream to the io.Reader returned by Claim().

func NewStdinReader

func NewStdinReader() *StdinReader

func (*StdinReader) Claim

func (r *StdinReader) Claim() io.ReadCloser

func (*StdinReader) Stop

func (r *StdinReader) Stop()
