Enum StoreError

    Log(LogError),
    CorruptTail {
        offset: u64,
        source: DecodeError,

}

Errors produced by Store.

Variants

Pipeline(PipelineError)

A pipeline stage (parse / bind / semantic / emit) rejected the batch. In-memory state and log are both untouched.

Log(LogError)

A filesystem / I/O failure during append, sync, or truncate. On commit-time failures the pipeline and log are rolled back to their pre-batch state before this error is returned.

CorruptTail

Non-recoverable bytes were found after the last durable CHECKPOINT during Store::open. Unlike crash-shaped orphan tails (Truncated / LengthMismatch) or valid uncommitted records, these bytes are preserved for inspection or restore rather than silently truncated.

Fields

offset: u64

Logical byte offset where corrupt tail decoding failed.

source: DecodeError

The underlying DecodeError from canonical::decode_record.

CorruptCommittedLog

The committed portion of the log (bytes before the last CHECKPOINT fsync) failed to decode during Store::open. This is distinct from tail recovery and indicates genuine corruption in the durable store.

Fields

source: DecodeError

The underlying DecodeError from canonical::decode_all.

DagReplay

A supersession edge replayed from the committed log failed its acyclicity check. The on-disk edges are expected to satisfy temporal-model.md § 6.2 invariant #1; surfacing as a typed error on open keeps silent invariant violations out of the reopened store.

Fields

source: DagError

The underlying DagError.

InvalidEpisodeMetadata

Supplied EpisodeMetadata violates a episode-semantics.md constraint — e.g. a label exceeding the 256-byte cap (§ 4.3).

Fields

reason: &'static str

Human-readable description of the failed constraint.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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.
