Struct CounterTracer 

pub struct CounterTracer { /* private fields */ }

Tracers Counter metrics that can increments only.

Implementations

impl CounterTracer

pub fn new(path: Path) -> Self

Creates a new tracer instance.

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

Increments value by the sepcific delta.

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>>, )

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.
