The error codes defined by QUIC Remember to run `go generate ./...` whenever the error codes change.

func (ErrorCode) Error

func (e ErrorCode) Error() string

func (ErrorCode) String

func (i ErrorCode) String() string

type QuicError

type QuicError struct {
	ErrorCode    ErrorCode
	ErrorMessage string
}

A QuicError consists of an error code plus a error reason

func Error

func Error(errorCode ErrorCode, errorMessage string) *QuicError

Error creates a new QuicError instance

func ToQuicError

func ToQuicError(err error) *QuicError

ToQuicError converts an arbitrary error to a QuicError. It leaves QuicErrors unchanged, and properly handles `ErrorCode`s.

func (*QuicError) Error

func (e *QuicError) Error() string

func (*QuicError) Timeout

func (e *QuicError) Timeout() bool
