Error types for topic pattern parsing

Variants

HashPosition

Hash wildcard (#) used not at the end of the pattern

Fields

pattern: String

The invalid pattern

WildcardUsage

Wildcard characters (+ or #) used incorrectly

Fields

usage: String

Description of invalid usage

EmptyTopic

Empty topic is not valid

PatternStructureMismatch

Topic pattern structure mismatch when trying to use compatible pattern

Fields

original: String

Original pattern from the struct

custom: String

Custom pattern that doesn’t match

Implementations

impl TopicPatternError

pub fn hash_position(pattern: impl Into<String>) -> TopicPatternError

Creates a new HashPosition error

pub fn wildcard_usage(usage: impl Into<String>) -> TopicPatternError

Creates a new WildcardUsage error

pub fn pattern_mismatch( original: impl Into<String>, custom: impl Into<String>, ) -> TopicPatternError

Creates a new PatternStructureMismatch error

Trait Implementations

impl Clone for TopicPatternError

fn clone(&self) -> TopicPatternError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopicPatternError

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

Formats the value using the given formatter.

impl Display for TopicPatternError

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

Formats the value using the given formatter.

impl Error for TopicPatternError

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<Infallible> for TopicPatternError

fn from(_: Infallible) -> TopicPatternError

Converts to this type from the input type.

impl From<TopicPatternError> for MqttClientError

fn from(source: TopicPatternError) -> MqttClientError

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<TopicPatternError> for TopicRouterError

fn from(source: TopicPatternError) -> TopicRouterError

Converts to this type from the input type.

impl PartialEq for TopicPatternError

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