Variants

InvalidOptionValue(Option<CoapOptionType>, OptionValueError)

Value of an option is invalid.

InvalidOptionForMessageType(CoapOptionType)

Message has an option that is specific for another message type (i.e., request option in response message).

NonRepeatableOptionRepeated(CoapOptionType)

Non-repeatable option was repeated.

NotACoapUri(UriParsingError)

Provided URI has invalid scheme.

InvalidUri(ParseError)

URI is invalid (most likely a Proxy URI cannot be parsed as a valid URL).

InvalidMessageCode(MessageCodeError)

Invalid message code.

DataInEmptyMessage

A message with code 0.00 (Empty) contains data.

MissingToken

Message has no token.

MissingMessageId

Message has no ID.

InvalidOptionCombination(CoapOptionTypeCoapOptionType)

Two (or more) options were combined which must not be combined (e.g., Proxy-Scheme and Proxy-URI).

CriticalOptionUnrecognized

A critical option (as defined in RFC 7252 was not recognized).

Unknown

Unknown error inside of libcoap.
