Struct QuantityMetric

pub struct QuantityMetric { /* private fields */ }

A quantity metric.

Used to store explicit non-negative integers.

Implementations

impl QuantityMetric

pub fn new(meta: CommonMetricData) -> Self

Creates a new quantity metric.

pub fn set(&self, value: i64)

Sets the value. Must be non-negative.

Arguments

• value - The value. Must be non-negative.

Notes

Logs an error if the value is negative.

pub fn test_get_value(&self, ping_name: Option<String>) -> Option<i64>

Test-only API (exported for FFI purposes).

Gets the currently stored value as an integer.

This doesn’t clear the stored value.

Arguments

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

Returns

The stored value or None if nothing stored.

pub fn test_get_num_recorded_errors(&self, error: ErrorType) -> i32

Exported for test purposes.

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

Arguments

• error - The type of error

Returns

The number of errors reported.
