}

A value that records metrics behind the facade.

Required methods

fn register_counter(&self, key: Key, description: Option<&'static str>)

Registers a counter.

Callers may provide a description of the counter being registered. Whether or not a metric can be reregistered to provide a description, if one was already passed or not, as well as how descriptions are used by the underlying recorder, is an implementation detail.

fn register_gauge(&self, key: Key, description: Option<&'static str>)

Registers a gauge.

Callers may provide a description of the counter being registered. Whether or not a metric can be reregistered to provide a description, if one was already passed or not, as well as how descriptions are used by the underlying recorder, is an implementation detail.

fn register_histogram(&self, key: Key, description: Option<&'static str>)

Registers a histogram.

Callers may provide a description of the counter being registered. Whether or not a metric can be reregistered to provide a description, if one was already passed or not, as well as how descriptions are used by the underlying recorder, is an implementation detail.

fn increment_counter(&self, key: Key, value: u64)

Increments a counter.

fn update_gauge(&self, key: Key, value: f64)

Updates a gauge.

fn record_histogram(&self, key: Key, value: u64)

Records a histogram.

The value can be value that implements [IntoU64]. By default, metrics provides an implementation for both u64 itself as well as Duration.
