Struct ValueRecorder

Source 
pub struct ValueRecorder<T>(/* private fields */);
Available on crate feature metrics only.
Expand description

ValueRecorder is a metric that records per-request non-additive values.

Implementations§

Source§

impl<T> ValueRecorder<T>
where T: Into<Number>,

Source

pub fn bind(&self, attributes: &[KeyValue]) -> BoundValueRecorder<T>

Creates a bound instrument for this ValueRecorder. The attributes are associated with values recorded via subsequent calls to record.

Source

pub fn record(&self, value: T, attributes: &[KeyValue])

Record a new metric value

Source

pub fn measurement(&self, value: T) -> Measurement

Creates a Measurement object to use with batch recording.
