FmtError formats e for logging.

GetErrorMsg extracts the message from e, if e implements the ErrorMsger interface.

GetNestedError returns the nested error, if any.

IsTemporaryErr determins if e is a temporary Error.

IsTimeoutErr determins if e is a temporary Error.

NewBasicError creates a new BasicError, with e as the embedded error (can be nil), with logCtx being a list of string/val pairs.

Maximum allowed hop-by-hop extensions, excluding a potential leading SCMP extension.

LineLen is the number of bytes that all SCION headers are padded to a multiple of.

BasicError is a simple error type that implements ErrorMsger and ErrorNester, and can contain context (slice of [string, val, string, val...]) for logging purposes.

ErrorMsger allows extracting the message from an error.

ErrorNester allows recursing into nested errors.

Temporary allows signalling of a temporary error.

Temporary allows signalling of a timeout error.
