Trait Implementations

impl Clone for MqttError

fn clone(&self) -> MqttError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MqttError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MqttError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MqttError

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

Formats the value using the given formatter.

impl Error for MqttError

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.

fn from(source: DecodeError) -> Self

Converts to this type from the input type.

impl From<EncodeError> for MqttError

fn from(source: EncodeError) -> Self

Converts to this type from the input type.

impl From<HandshakeError> for MqttError

fn from(source: HandshakeError) -> Self

Converts to this type from the input type.

impl From<ProtocolError> for MqttError

fn from(source: ProtocolError) -> Self

Converts to this type from the input type.

impl From<SendPacketError> for MqttError

fn from(source: SendPacketError) -> Self

Converts to this type from the input type.

impl Serialize for MqttError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToReasonCode for MqttError

fn to_reason_code(&self) -> DisconnectReasonCode
