Enum MetricSourceError 

pub enum MetricSourceError {
    ErrorRetrievingCounters,
    InitTimeout(Duration),
    SourceError(Box<dyn Error + Send + Sync>),
}

Errors that can occur when reading or aggregating metrics from a source.

This enum is used by all metric sources implementing MetricReader to signal failures during measurements.

Variants

ErrorRetrievingCounters

The source failed to retrieve its internal counters.

InitTimeout(Duration)

The initialization of the source lasted more than the authorized time.

SourceError(Box<dyn Error + Send + Sync>)

Error propagated from a custom metric source.

Trait Implementations

impl Debug for MetricSourceError

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

Formats the value using the given formatter.

impl Display for MetricSourceError

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

Formats the value using the given formatter.

impl Error for MetricSourceError

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<Box<dyn Error + Sync + Send>> for MetricSourceError

fn from(source: Box<dyn Error + Send + Sync>) -> Self

Converts to this type from the input type.

impl From<MetricSourceError> for JouleProfilerError

fn from(source: MetricSourceError) -> Self
