Enum SourceError 

#[non_exhaustive]
pub enum SourceError {
    Connection(String),
    Setup(String),
    Decode(String),
    Query(String),
    Unsupported(String),
}

Why a ChangeCapture failed to start or to produce the next change.

The split that matters to the engine is transient vs. fatal: Connection is worth retrying (resume picks up from the last confirmed point), while Setup needs operator intervention.

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.

Connection(String)

The connection to Postgres dropped or could not be established. Transient: the engine may retry, and the mechanism resumes from its last confirmed point.

Setup(String)

Setup the mechanism depends on is missing or invalid — a dropped replication slot, a missing publication, wal_level too low, missing privileges. Not recoverable by retrying.

Decode(String)

A raw change could not be decoded into a Change.

Query(String)

A query against the source failed (assembling or resolving a document).

Unsupported(String)

The configuration uses a feature the active source implementation does not support yet.

Trait Implementations

impl Debug for SourceError

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

Formats the value using the given formatter.

impl Display for SourceError

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

Formats the value using the given formatter.

impl Error for SourceError

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>)
