Struct PubsubError

pub struct PubsubError;

Error type returned when a Pubsub operation fails.

This error occurs when:

• The Pubsub system has been closed and no more messages can be received
• A subscriber attempts to receive a message after the Pubsub system has been dropped

Examples

// let pubsub = Pubsub::new();
// let subscriber = pubsub.subscribe(vec!["topic1"]).await;
// drop(pubsub);
// let result = subscriber.recv().await;
// assert!(matches!(result, Err(PubsubError)));

Trait Implementations

impl Clone for PubsubError

fn clone(&self) -> PubsubError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PubsubError

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

Formats the value using the given formatter.

impl Display for PubsubError

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

Formats the value using the given formatter.

impl Error for PubsubError

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 PartialEq for PubsubError

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