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(CoapOptionType, CoapOptionType)

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.

Trait Implementations

impl Clone for MessageConversionError

fn clone(&self) -> MessageConversionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageConversionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MessageConversionError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

impl Eq for MessageConversionError

impl Error for MessageConversionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
