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.

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 copy 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

Formats the value using the given formatter.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<MessageCodeError> for MessageConversionError

fn from(source: MessageCodeError) -> Self

Converts to this type from the input type.

impl From<UriParsingError> for MessageConversionError

fn from(v: UriParsingError) -> Self

Converts to this type from the input type.

impl PartialEq for MessageConversionError

fn eq(&self, other: &MessageConversionError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
