Struct glean::private::CustomDistributionMetric

pub struct CustomDistributionMetric { /* private fields */ }

A custom distribution metric.

Memory distributions are used to accumulate and store memory sizes.

Implementations

impl CustomDistributionMetric

pub fn new(
    meta: CommonMetricData,
    range_min: i64,
    range_max: i64,
    bucket_count: i64,
    histogram_type: HistogramType
) -> CustomDistributionMetric

Creates a new memory distribution metric.

pub fn accumulate_samples(&self, samples: Vec<i64, Global>)

Accumulates the provided signed samples in the metric.

This is required so that the platform-specific code can provide us with 64 bit signed integers if no u64 comparable type is available. This will take care of filtering and reporting errors for any provided negative sample.

Arguments

• samples - The vector holding the samples to be recorded by the metric.

Notes

Discards any negative value in samples and report an ErrorType::InvalidValue for each of them.

pub fn test_get_value(
    &self,
    ping_name: Option<String>
) -> Option<DistributionData>

Test-only API (exported for FFI purposes).

Gets the currently stored value as an integer.

This doesn’t clear the stored value.

pub fn test_get_num_recorded_errors(
    &self,
    error: ErrorType,
    ping_name: Option<String>
) -> i32

Exported for test purposes.

Gets the number of recorded errors for the given metric and 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 reported.
