Struct rill_engine::tracers::tracer::Tracer

pub struct Tracer<T: Flow> { /* fields omitted */ }

The generic provider that forwards metrics to worker and keeps a flag for checking the activitiy status of the Tracer.

Implementations

impl<T: Flow> Tracer<T>

pub fn new(state: T, path: Path, pull_interval: Option<Duration>) -> Self

Create a new Tracer

pub fn new_push(state: T, path: Path) -> Self

Create a Push mode Tracer

pub fn new_pull(state: T, path: Path, interval: Duration) -> Self

Create a Pull mode Tracer

pub fn path(&self) -> &Path

Returns a reference to a Path of the Tracer.

pub fn description(&self) -> &Description

Returns a reference to a Description of the Tracer.

pub fn send(
    &self,
    event: T::Event,
    direction: Option<Direction<ProviderProtocol>>
)

Send an event to a Recorder.

pub fn flush(&self)

Ask recorder to resend a state in the Pull mode.

pub fn sync_callback<F>(&self, callback: F) where
    F: Fn(ActionEnvelope<T>) -> Result<(), Error>,
    F: Send + Sync + 'static, 

Assign a callback

pub fn detach_callback(&self)

Removes the callback

Trait Implementations

impl<T: Flow> Clone for Tracer<T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + Flow> Debug for Tracer<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Flow> PartialEq<Tracer<T>> for Tracer<T>

Both tracers are equal only if they use the same description. That means they both have the same recorder/channel.

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
