pub struct StringMetric { /* private fields */ }

A string metric.

Implementations

impl StringMetric

pub fn new(meta: CommonMetricData) -> StringMetric

Creates a new string metric.

pub fn set(&self, value: String)

Sets to the specified value.

Arguments

• value - The string to set the metric to.

Notes

Truncates the value if it is longer than MAX_LENGTH_VALUE bytes and logs an error.

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

Test-only API (exported for FFI purposes).

Gets the currently stored value as a string.

This doesn’t clear the stored value.

pub fn test_get_num_recorded_errors(
    &self,
    error: ErrorType,

) -> i32

Exported for test purposes.
