Errors returned by the Apache Pulsar broker.

One enum for the whole crate, variants by source, per the RustStream broker conventions. The wrapped sources are boxed std errors so the public API does not leak the client’s error types.

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.

Connect(Box<dyn StdError + Send + Sync>)

Establishing the client connection failed.

Subscribe

Creating a consumer failed.

Fields

topic: String

The topic (or pattern) the subscription targeted.

source: Box<dyn StdError + Send + Sync>

The client’s failure.

Receive

The consumer stream failed or ended permanently.

Fields

topic: String

The topic (or pattern) of the subscription.

source: Box<dyn StdError + Send + Sync>

The client’s failure.

Publish

Creating a producer or sending a message failed.

Fields

topic: String

The topic the message targeted.

source: Box<dyn StdError + Send + Sync>

NotConnected

The handle is used before connect filled the shared connection, or after shutdown.

Invalid(String)

impl Error for PulsarError

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.
