Failure of a pure measurement state transition or snapshot validation.

Variants

CounterOverflow

A checked counter update exceeded u64::MAX.

Fields

metric: Metric

Counter that could not represent the next value.

ClockRegression

An event or query moved behind the current record time.

Fields

observed: UnixTime

Timestamp supplied by the adapter.

current: UnixTime

Latest timestamp or aligned epoch already represented by the record.

ReliabilityWindowMismatch

A live record was used with a different reliability window.

Fields

stored_seconds: u64

Window stored with the retained reliability epoch.

supplied_seconds: u64

Window supplied by the caller for this operation.

UnsupportedSnapshotVersion

A snapshot uses a schema version this crate cannot interpret.

Fields

found: u16

Unrecognized schema version.

SnapshotPeerLimitExceeded

A snapshot contains more peer records than the configured ledger bound.

Fields

found: usize

Number of records encoded in the snapshot.

max: usize

Configured maximum number of retained peer records.

DuplicatePeerInSnapshot

A snapshot contains more than one record for the same peer key.

SnapshotEvidenceWithoutEpoch

A snapshot stores reliability evidence without a timestamped epoch.

SnapshotEpochWithoutEvidence

A snapshot stores an epoch even though its reliability bucket is empty.

SnapshotReliabilityWindowMissing

A snapshot reliability epoch has no associated window policy.

SnapshotReliabilityWindowWithoutEpoch

A snapshot stores a reliability policy without an observed epoch.

SnapshotReliabilityEpochMisaligned

A snapshot reliability epoch is not aligned to its stored window.

Trait Implementations

impl Clone for MeasureError

fn clone(&self) -> MeasureError

Returns a duplicate of the value.

impl Copy for MeasureError

impl Debug for MeasureError

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

impl Eq for MeasureError

impl Error for MeasureError

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 MeasureError

fn eq(&self, other: &MeasureError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
