Enum StreamConsumerError 

#[non_exhaustive]
pub enum StreamConsumerError {
    ActiveConsumer {
        stream_name: &'static str,
    },
}

Errors that can occur when creating a stream consumer.

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.

ActiveConsumer

A single-subscriber stream already has an active consumer.

Fields

stream_name: &'static str

The name of the stream that rejected the consumer.

Implementations

impl StreamConsumerError

pub fn stream_name(&self) -> &'static str

The name of the stream that rejected the consumer.

Trait Implementations

impl Clone for StreamConsumerError

fn clone(&self) -> StreamConsumerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamConsumerError

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

Formats the value using the given formatter.

impl Display for StreamConsumerError

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

Formats the value using the given formatter.

impl Error for StreamConsumerError

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 StreamConsumerError

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