Crate zipkin

Zipkin is a library for collecting timing information about computations in distributed systems. This information is collected into Zipkin spans.

This library corresponds to version 2 of the Zipkin specification.

Serialization

If the serde Cargo feature is enabled, Annotation, Endpoint, Kind, Span, SpanId, and TraceId implement Serialize and Deserialize in the standard Zipkin format.

Modules

annotation

Annotations.

endpoint

Endpoints.

report

Span reporters.

sample

Span samplers.

sampling_flags

Sampling flags.

span

Spans.

span_id

Span IDs.

trace_context

Trace contexts.

trace_id

Trace IDs.

tracer

Tracers.

Structs

Annotation

Associates an event that explains latency with a timestamp.

Attached

A type indicating that an OpenSpan is “attached” to the tracer’s with respect to context management.

Detached

A type indicating that an OpenSpan is “detached” from the tracer’s with respect to context management.

Endpoint

The network context of a node in the service graph.

OpenSpan

An open span.

SamplingFlags

Flags used to control sampling.

Span

A Span represents a single operation over some range of time.

SpanId

The ID of a span.

TraceContext

A TraceContext represents a distributed trace request.

TraceId

The ID of a trace.

Tracer

The root tracing object.

Enums

Kind

The “kind” of a span.

Traits

Attachment

A marker trait for types which parameterize an OpenSpan’s attachment.

Report

A reporter consumes Zipkin spans and reports them.

Sample

A sampler decides whether or not a span should be recorded based on its trace ID.
