Failure while reading or mutating one stateful metric.

Variants

OperationNotOpen

The enclosing operation is freezing or already closed.

Fields

metric_id: String

Stable metric ID.

state: OperationLifecycle

Lifecycle state that rejected the transition.

InsufficientActive

A completion delta attempted to consume more active work than exists.

Fields

metric_id: String

Stable metric ID.

requested: u64

Total terminal work requested by the delta.

available: u64

Active work available at the linearization point.

TotalExceeded

A transition would exceed the configured total.

Fields

metric_id: String

Stable metric ID.

total: u64

Configured total.

attempted: u64

Attempted occupied count.

CountOverflow

Metric arithmetic overflowed.

Fields

metric_id: String

Stable metric ID.

Trait Implementations

impl Clone for MetricError

fn clone(&self) -> MetricError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricError

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

Formats the value using the given formatter.

impl Display for MetricError

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

Formats the metric transition failure.

impl Eq for MetricError

impl Error for MetricError

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 MetricError

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

Equality operator ==.

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

Inequality operator !=.
