Functions

func CopyContext

func CopyContext(ctx context.Context, dst DeadlineWriter, src DeadlineReader) (written int64, err error)

CopyContext is equivalent to `io.Copy` but with context cancellation support (for deadline reader/writers).

func Pipe

func Pipe() (*PipeReader, *PipeWriter)

Pipe is equivalent to `io.Pipe` but with deadline support.
