    },

}

Replay errors returned by derived-state feed sources.

Variants

SessionUnavailable(FeedSessionId)

No retained session was available for the requested checkpoint.

SequenceGap

The retained feed did not contain the expected contiguous next sequence.

Fields

session_id: FeedSessionId

Session that contained the gap.

sequence: FeedSequence

First missing or mismatched sequence.

Truncated

The replay source truncated older envelopes before the requested sequence.

Fields

session_id: FeedSessionId

Session that retained only a later tail.

sequence: FeedSequence

First requested sequence that was no longer retained.

oldest_retained_sequence: FeedSequence

Oldest sequence still retained for the session.

BackendFailure

The replay backend could not load or decode the retained feed.

Fields

session_id: FeedSessionId

Session whose retained log could not be loaded.

message: String

Free-form backend diagnostic.

Trait Implementations

impl Clone for DerivedStateReplayError

fn clone(&self) -> DerivedStateReplayError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DerivedStateReplayError

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

Formats the value using the given formatter.

impl Display for DerivedStateReplayError

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

Formats the value using the given formatter.

impl Error for DerivedStateReplayError

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 DerivedStateReplayError

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