A description for the NumeratorMetric subtype of the RateMetric type.

Required Methods

fn add_to_numerator(&self, amount: i32)

Increases the numerator by amount.

Arguments

• amount - The amount to increase by. Should be non-negative.

Notes

Logs an error if the amount is negative.

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

Exported for test purposes.

Gets the currently stored value as a pair of integers.

Arguments

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

This doesn’t clear the stored value.

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.
