Enum MetricError

#[non_exhaustive]
pub enum MetricError {
    Other(String),
    Config(String),
    ExportErr(Box<dyn ExportError>),
    InvalidInstrumentConfiguration(&'static str),
}

Errors returned by the metrics API.

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.

Other(String)

Other errors not covered by specific cases.

Config(String)

Invalid configuration

ExportErr(Box<dyn ExportError>)

Fail to export metrics

InvalidInstrumentConfiguration(&'static str)

Invalid instrument configuration such invalid instrument name, invalid instrument description, invalid instrument unit, etc. See spec for full list of requirements.

Trait Implementations

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 value using the given formatter.

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 From<MetricError> for Error

fn from(source: MetricError) -> Self

impl<T> From<PoisonError<T>> for MetricError

fn from(err: PoisonError<T>) -> Self

Converts to this type from the input type.

impl<T: ExportError> From<T> for MetricError

fn from(err: T) -> Self

Converts to this type from the input type.
