Struct HistogramTracer 

pub struct HistogramTracer { /* private fields */ }

Tracers Histogram metrics.

Implementations

impl HistogramTracer

pub fn new(path: Path, levels: Vec<f64>) -> Self

Creates a new tracer instance.

pub fn add(&self, value: f64, timestamp: Option<SystemTime>)

Add value of the histogram.

Methods from Deref<Target = Tracer<HistogramState>>

pub fn path(&self) -> &Path

Returns a reference to a Path of the Tracer.

pub fn send( &self, data: <T as Flow>::Event, opt_system_time: Option<SystemTime>, direction: Option<Direction<ProviderProtocol>>, )

Send an event to a Recorder.

pub fn subscribe(&mut self) -> Result<Receiver<ActionEnvelope<T>>, Error>

Subscribe to the stream of the watcher.

pub fn callback<F>(&mut self, func: F)

where F: Fn(ActionEnvelope<T>) + Send + 'static,

Registers a callback to the flow.

pub fn is_active(&self) -> bool

Returns true is the Tracer has to send data.
