Trait cadence::Counted [−] [src]

pub trait Counted {
    fn incr(&self, key: &str) -> MetricResult<Counter>;
    fn decr(&self, key: &str) -> MetricResult<Counter>;
    fn count(&self, key: &str, count: i64) -> MetricResult<Counter>;
}

Trait for incrementing and decrementing counters.

Counters are simple values incremented or decremented by a client. The rates at which these events occur or average values will be determined by the server receiving them. Examples of counter uses include number of logins to a system or requests received.

See the Statsd spec for more information.

Required Methods

`fn incr(&self, key: &str) -> MetricResult<Counter>`

Increment the counter by 1

`fn decr(&self, key: &str) -> MetricResult<Counter>`

Decrement the counter by 1

`fn count(&self, key: &str, count: i64) -> MetricResult<Counter>`

Increment or decrement the counter by the given amount
