Crate tracing_distributed[−][src]
Expand description
This crate provides:
TelemetryLayer
, a generic tracing layer that handles publishing spans and events to arbitrary backends- Utilities for implementing distributed tracing for arbitrary backends
As a tracing layer, TelemetryLayer
can be composed with other layers to provide stdout logging, filtering, etc.
This crate is primarily intended to be used by people implementing their own backends.
A concrete implementation using honeycomb.io as a backend is available in the tracing-honeycomb
crate.
Structs
Telemetry implementation that does not publish information to any backend. For use in tests.
An Event
holds ready-to-publish information derived from a tracing::Event
.
A Span
holds ready-to-publish information gathered during the lifetime of a tracing::Span
.
A tracing_subscriber::Layer
that publishes events and spans to some backend
using the provided Telemetry
capability.
Enums
Errors that can occur while registering the current span as a distributed trace root or attempting to retrieve the current trace context.
Traits
Represents the ability to publish events and spans to some arbitrary backend.
Functions
Retrieve the distributed trace context associated with the current span. Returns the
TraceId
, if any, that the current span is associated with along with the SpanId
belonging to the current span.
Register the current span as the local root of a distributed trace.
