Enum TopicMatcherError 

pub enum TopicMatcherError {
    EmptyTopicPath,
    InvalidSegment {
        segment: String,
        position: usize,
    },
    InvalidUtf8 {
        details: String,
    },
}

Errors that can occur during topic matching operations

Variants

EmptyTopicPath

Topic path provided for matching is empty

InvalidSegment

Invalid topic segment encountered during matching

Fields

segment: String

The offending segment value.

position: usize

Zero-based position of the segment within the path.

InvalidUtf8

Topic path contains invalid UTF-8 characters

Fields

details: String

Details about the decoding failure.

Implementations

impl TopicMatcherError

pub fn invalid_segment(segment: impl Into<String>, position: usize) -> Self

Creates a new InvalidSegment error

pub fn invalid_utf8(details: impl Into<String>) -> Self

Creates a new InvalidUtf8 error

Trait Implementations

impl Clone for TopicMatcherError

fn clone(&self) -> TopicMatcherError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopicMatcherError

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

Formats the value using the given formatter.

impl Display for TopicMatcherError

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

Formats the value using the given formatter.

impl Eq for TopicMatcherError

impl Error for TopicMatcherError

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<TopicMatcherError> for TopicError

fn from(source: TopicMatcherError) -> Self

Converts to this type from the input type.

impl From<TopicMatcherError> for TopicRouterError

fn from(source: TopicMatcherError) -> Self

Converts to this type from the input type.

impl PartialEq for TopicMatcherError

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