Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoMetrics

An operation was started without metrics.

EmptyMetricId

A metric ID is empty or whitespace only.

Fields

index: usize

Zero-based metric position in the builder.

EmptyMetricName

A metric name is empty or whitespace only.

Fields

metric_id: String

ID of the malformed metric.

DuplicateMetricId

Two configured metrics have the same ID.

Fields

metric_id: String

Duplicated stable metric ID.

EmptyAttributeKey

An operation attribute key is empty or whitespace only.

Fields

key: String

Malformed attribute key.

EmptyStageId

A stage ID is empty or whitespace only.

EmptyStageName

A stage name is empty or whitespace only.

IncompleteStagePosition

Stage position and total were not supplied together.

InvalidStagePosition

Stage position is outside its one-based total range.

Fields

position: u64

Invalid one-based position.

total: u64

Declared number of stages.

Trait Implementations

impl Clone for ConfigurationError

fn clone(&self) -> ConfigurationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConfigurationError

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

Formats the value using the given formatter.

impl Display for ConfigurationError

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

Formats a concise configuration explanation.

impl Eq for ConfigurationError

impl Error for ConfigurationError

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 From<ConfigurationError> for StartError

fn from(error: ConfigurationError) -> Self

Converts configuration validation into a start failure.

impl PartialEq for ConfigurationError

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

Equality operator ==.

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

Inequality operator !=.
