[−][src]Struct glean_core::metrics::CounterMetric
A counter metric.
Used to count things. The value can only be incremented, not decremented.
Implementations
impl CounterMetric
[src]
pub fn new(meta: CommonMetricData) -> Self
[src]
Create a new counter metric.
pub fn add(&self, glean: &Glean, amount: i32)
[src]
Increase the counter by amount
.
Arguments
glean
- The Glean instance this metric belongs to.amount
- The amount to increase by. Should be positive.
Notes
Logs an error if the amount
is 0 or negative.
pub fn test_get_value(&self, glean: &Glean, storage_name: &str) -> Option<i32>
[src]
Test-only API (exported for FFI purposes).
Get the currently stored value as an integer.
This doesn't clear the stored value.
