Struct PulseTracer 

pub struct PulseTracer { /* private fields */ }

Sends metrics as pulse that can change value to any.

Implementations

impl PulseTracer

pub fn new(path: Path, depth: Option<u32>) -> Self

Creates a new Pulse tracer.

pub fn inc(&self, delta: f64, timestamp: Option<SystemTime>)

Increments the value by the specific delta.

pub fn dec(&self, delta: f64, timestamp: Option<SystemTime>)

Decrements the value by the specific delta.

pub fn set(&self, new_value: f64, timestamp: Option<SystemTime>)

Set the value.

Methods from Deref<Target = Tracer<PulseState>>

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.
