Enum RestoreError 

pub enum RestoreError {
    PhaseFailed {
        lifecycle: Lifecycle,
        frame_seq: u64,
        message: String,
    },
    TornWriteMidStream {
        frame_seq: u64,
        reason: String,
    },
    BaselineMissing,

    },
    WalTierRequired,
}

Replay-time failures from Graph::restore_snapshot({ mode: "diff" }).

Variants

PhaseFailed

A phase’s batch() rejected. lifecycle and frame_seq identify the boundary; message carries the underlying cause. Earlier phases stay committed (Q2 partial-restore semantics).

Fields

lifecycle: Lifecycle

frame_seq: u64

message: String

TornWriteMidStream

A mid-stream frame’s checksum mismatched and the on_torn_write policy resolved to “abort”. The Q3 default is “abort” for mid-stream (vs “skip” for WAL tail).

Fields

frame_seq: u64

reason: String

BaselineMissing

restore_snapshot({ mode: "diff" }) ran with no mode:"full" baseline in the snapshot tier — replay needs a starting point.

CodecMismatch

A frame’s format_version doesn’t match the tier’s configured codec. Distinct from StorageError::CodecMismatch which is tier-level; this one is replay-time.

Fields

frame_seq: u64

expected: String

found: String

WalTierRequired

Caller passed a source: { tier } shape without a wal_tier when the snapshot tier itself doesn’t carry WAL frames. Distinct from StorageError::BackendNoListSupport because the diagnostic is “you forgot to wire the WAL tier”, not “the backend can’t enumerate”.

Trait Implementations

impl Debug for RestoreError

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

Formats the value using the given formatter.

impl Display for RestoreError

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

Formats the value using the given formatter.

impl Error for RestoreError

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.
