Implementations

impl TopicRouterError

pub fn subscription_not_found(id: SubscriptionId) -> TopicRouterError

Creates a new SubscriptionNotFound error

pub fn invalid_routing_topic( topic: impl Into<String>, reason: impl Into<String>, ) -> TopicRouterError

Creates a new InvalidRoutingTopic error

pub fn internal_state_corrupted(details: impl Into<String>) -> TopicRouterError

Creates a new InternalStateCorrupted error

Trait Implementations

impl Clone for TopicRouterError

fn clone(&self) -> TopicRouterError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopicRouterError

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

Formats the value using the given formatter.

impl Display for TopicRouterError

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

Formats the value using the given formatter.

impl Eq for TopicRouterError

impl Error for TopicRouterError

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 TopicRouterError

fn from(source: TopicMatcherError) -> TopicRouterError

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 From<TopicRouterError> for TopicError

fn from(source: TopicRouterError) -> TopicError

Converts to this type from the input type.

impl PartialEq for TopicRouterError

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