Enum ConnectError 

pub enum ConnectError {
    Io(Error),
    Convert(String),
    Offset(String),
    Transaction(String),
    Backend(String),
}

Errors raised by Source, Sink, and Converter implementations.

Variants

Io(Error)

An I/O failure talking to the external system (socket, file, …).

Convert(String)

Serializing or deserializing a record payload failed. Wraps converter failures, e.g. a schema-registry serde rejecting a value or a writer schema not yet resolved.

Offset(String)

A checkpoint could not be produced, or a SourceOffset handed back to Source::seek does not name a position this source can resume from.

Transaction(String)

A transactional Sink operation failed (begin / commit / abort), or transactional methods were driven against a sink that does not support them.

Backend(String)

A backend error that does not map cleanly onto one of the structured variants above.

Trait Implementations

impl Debug for ConnectError

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

Formats the value using the given formatter.

impl Display for ConnectError

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

Formats the value using the given formatter.

impl Error for ConnectError

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<Error> for ConnectError

fn from(source: Error) -> Self

Converts to this type from the input type.
