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.

Structs

Annotation	Associates an event that explains latency with a timestamp.
Attached	A type indicating that an OpenSpan is "attached" to the current thread.
Bind	A type which wraps a future, associating it with an OpenSpan.
CurrentGuard	A guard object for the thread-local current trace context.
Detached	A type indicating that an OpenSpan is "detached" from the current thread.
Endpoint	The network context of a node in the service graph.
OpenSpan	An open span.
SamplingFlags	Flags used to control sampling.
SetTracerError	The error returned when attempting to set a tracer when one is already installed.
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.

Enums

Kind	The "kind" of a span.

Traits

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.

Functions

current	Returns this thread's current trace context.
join_trace	Joins an existing trace.
new_child	Stats a new span with the specified parent.
new_trace	Starts a new trace.
new_trace_from	Stats a new trace with specific sampling flags.
next_span	Creates a new span parented to the current one if it exists, or starting a new trace otherwise.
set_current	Sets this thread's current trace context.
set_tracer	Initializes the global tracer.

Attribute Macros

spanned

Wraps the execution of a function or method in a span.
