Struct tracing_distributed::TelemetryLayer

pub struct TelemetryLayer<Telemetry, SpanId, TraceId> { /* fields omitted */ }

A tracing_subscriber::Layer that publishes events and spans to some backend using the provided Telemetry capability.

Implementations

impl<T, SpanId, TraceId> TelemetryLayer<T, SpanId, TraceId> where
    SpanId: 'static + Clone + Send + Sync,
    TraceId: 'static + Clone + Send + Sync, 

pub fn new<F: 'static + Send + Sync + Fn(Id) -> SpanId>(
    service_name: &'static str,
    telemetry: T,
    promote_span_id: F
) -> Self

Construct a new TelemetryLayer using the provided Telemetry capability. Uses the provided function, F, to promote tracing::span::Id instances to the SpanId type associated with the provided Telemetry instance.

Trait Implementations

impl<S, TraceId, SpanId, V, T> Layer<S> for TelemetryLayer<T, SpanId, TraceId> where
    S: Subscriber + for<'a> LookupSpan<'a>,
    TraceId: 'static + Clone + Eq + Send + Sync,
    SpanId: 'static + Clone + Eq + Send + Sync,
    V: 'static + Visit + Send + Sync,
    T: 'static + Telemetry<Visitor = V, TraceId = TraceId, SpanId = SpanId>, 

fn new_span(&self, attrs: &Attributes<'_>, id: &Id, ctx: Context<'_, S>)

Notifies this layer that a new span was constructed with the given Attributes and Id.

fn on_record(&self, id: &Id, values: &Record<'_>, ctx: Context<'_, S>)

Notifies this layer that a span with the given Id recorded the given values.

fn on_event(&self, event: &Event<'_>, ctx: Context<'_, S>)

Notifies this layer that an event has occurred.

fn on_close(&self, id: Id, ctx: Context<'_, S>)

Notifies this layer that the span with the given ID has been closed.

unsafe fn downcast_raw(&self, id: TypeId) -> Option<*const ()>

pub fn register_callsite(
    &self,
    metadata: &'static Metadata<'static>
) -> Interest

Registers a new callsite with this layer, returning whether or not the layer is interested in being notified about the callsite, similarly to Subscriber::register_callsite.

pub fn enabled(&self, metadata: &Metadata<'_>, ctx: Context<'_, S>) -> bool

Returns true if this layer is interested in a span or event with the given metadata in the current Context, similarly to Subscriber::enabled.

pub fn on_follows_from(&self, _span: &Id, _follows: &Id, _ctx: Context<'_, S>)

Notifies this layer that a span with the ID span recorded that it follows from the span with the ID follows.

pub fn on_enter(&self, _id: &Id, _ctx: Context<'_, S>)

Notifies this layer that a span with the given ID was entered.

pub fn on_exit(&self, _id: &Id, _ctx: Context<'_, S>)

Notifies this layer that the span with the given ID was exited.

pub fn on_id_change(&self, _old: &Id, _new: &Id, _ctx: Context<'_, S>)

Notifies this layer that a span ID has been cloned, and that the subscriber returned a different ID.

pub fn and_then<L>(self, layer: L) -> Layered<L, Self, S> where
    L: Layer<S>, 

Composes this layer around the given Layer, returning a Layered struct implementing Layer.

pub fn with_subscriber(self, inner: S) -> Layered<Self, S, S>

Composes this Layer with the given Subscriber, returning a Layered struct that implements Subscriber.
