Required methods
fn register_counter(
&self,

)
&self,
key: Key,
unit: Option<Unit>,
description: Option<&'static str>
)
Registers a counter.
Callers may provide the unit or a description of the counter being registered. Whether or not a metric can be reregistered to provide a unit/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,
unit: Option<Unit>,
description: Option<&'static str>
)
&self,
key: Key,
unit: Option<Unit>,
description: Option<&'static str>
)
Registers a gauge.
Callers may provide the unit or a description of the gauge being registered. Whether or not a metric can be reregistered to provide a unit/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,
unit: Option<Unit>,
description: Option<&'static str>
)
&self,
key: Key,
unit: Option<Unit>,
description: Option<&'static str>
)
Registers a histogram.
Callers may provide the unit or a description of the histogram being registered. Whether or not a metric can be reregistered to provide a unit/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.
