Enum ParseTopicError 

#[non_exhaustive]
pub enum ParseTopicError {
    Topic(TopicError),
    Data(DataError),
}

Error returned when parsing a topic from an unvalidated string.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Topic(TopicError)

The string violates topic name or filter rules.

Data(DataError)

The string violates MQTT data encoding constraints.

Trait Implementations

impl Clone for ParseTopicError

fn clone(&self) -> ParseTopicError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseTopicError

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

Formats the value using the given formatter.

impl Display for ParseTopicError

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

Formats the value using the given formatter.

impl Error for ParseTopicError

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<DataError> for ParseTopicError

fn from(value: DataError) -> Self

Converts to this type from the input type.

impl From<TopicError> for ParseTopicError

fn from(value: TopicError) -> Self

Converts to this type from the input type.

impl PartialEq for ParseTopicError

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