A description for the MemoryDistributionMetric type.

When changing this trait, make sure all the operations are implemented in the related type in ../metrics/.

Required methods

fn accumulate(&self, sample: u64)

Accumulates the provided sample in the metric.

Arguments

• sample - The sample to be recorded by the metric. The sample is assumed to be in the configured memory unit of the metric.

Notes

Values bigger than 1 Terabyte (2⁴⁰ bytes) are truncated and an ErrorType::InvalidValue error is recorded.

fn test_get_value<'a, S>(&self, ping_name: S) -> Option<DistributionData> where
    S: Into<Option<&'a str>>, 

Exported for test purposes.

Gets the currently stored value as a DistributionData of the serialized value.

This doesn’t clear the stored value.

Arguments

• ping_name - represents the optional name of the ping to retrieve the metric for. Defaults to the first value in send_in_pings.

fn test_get_num_recorded_errors<'a, S>(
    &self,
    error: ErrorType,
    ping_name: S
) -> i32 where
    S: Into<Option<&'a str>>, 

Exported for test purposes.

Gets the number of recorded errors for the given error type.

Arguments

• error - The type of error
• ping_name - represents the optional name of the ping to retrieve the metric for. Defaults to the first value in send_in_pings.

Returns

The number of errors recorded.
