Enum TopicError

pub enum TopicError {
    Pattern(TopicPatternError),
    Format(TopicFormatError),
    Matcher(TopicMatcherError),
    Router(TopicRouterError),
}

Comprehensive error type for all topic-related operations

This enum aggregates all possible errors that can occur within the topic module, providing a single error type for the public API while maintaining detailed error information from each submodule.

Variants

Pattern(TopicPatternError)

Topic pattern parsing or validation error

Format(TopicFormatError)

Topic formatting error when substituting parameters

Matcher(TopicMatcherError)

Topic matching operation error

Router(TopicRouterError)

Topic routing operation error

Trait Implementations

impl Clone for TopicError

fn clone(&self) -> TopicError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopicError

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

Formats the value using the given formatter.

impl Display for TopicError

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

Formats the value using the given formatter.

impl Error for TopicError

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<TopicError> for MqttClientError

fn from(source: TopicError) -> MqttClientError

Converts to this type from the input type.

impl From<TopicFormatError> for TopicError

fn from(source: TopicFormatError) -> TopicError

Converts to this type from the input type.

impl From<TopicMatcherError> for TopicError

fn from(source: TopicMatcherError) -> TopicError

Converts to this type from the input type.

impl From<TopicPatternError> for TopicError

fn from(source: TopicPatternError) -> TopicError

Converts to this type from the input type.

impl From<TopicRouterError> for TopicError

fn from(source: TopicRouterError) -> TopicError

Converts to this type from the input type.

impl PartialEq for TopicError

fn eq(&self, other: &TopicError) -> 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.
