Enum ConsumerError 

#[non_exhaustive]
pub enum ConsumerError {
    TaskJoin {
        stream_name: &'static str,
        source: JoinError,
    },
    StreamRead {
        source: StreamReadError,
    },
}

Errors that the Consumer infrastructure itself can raise while driving its stream.

These describe failures of the consumer task — joining, or reading the underlying stream. Visitor-specific failures (for example, a write-backed visitor’s sink rejecting bytes) live in the visitor’s own StreamVisitor::Output / AsyncStreamVisitor::Output type, not here. So a writer-backed consumer’s wait returns Result<Result<W, SinkWriteError>, ConsumerError>: the outer result is what ConsumerError describes, the inner is the writer visitor’s own outcome.

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.

TaskJoin

The consumer task could not be joined/terminated.

Fields

stream_name: &'static str

The name of the stream this consumer operates on.

source: JoinError

The source error.

StreamRead

The underlying stream failed while being read.

Fields

source: StreamReadError

The source error.

Trait Implementations

impl Debug for ConsumerError

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

Formats the value using the given formatter.

impl Display for ConsumerError

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

Formats the value using the given formatter.

impl Error for ConsumerError

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.
