Module opentelemetry::sdk::trace[−][src]

This is supported on crate feature trace only.

OpenTelemetry Trace SDK

The tracing SDK consist of a few main structs:

The Tracer struct which performs all tracing operations.
The Span struct with is a mutable object storing information about the current operation execution.
The TracerProvider struct which configures and produces Tracers.

BatchConfig	Batch span processor configuration
BatchSpanProcessor	A `SpanProcessor` that asynchronously buffers finished spans and reports them at a preconfigured interval.
BatchSpanProcessorBuilder	A builder for creating `BatchSpanProcessor` instances.
Builder	Builder for provider attributes.
Config	Tracer configuration
EvictedHashMap	A hash map with a capped number of attributes that retains the most recently set entries.
EvictedQueue	This queue maintains an ordered list of elements, and a count of dropped elements. Elements are removed from the queue in a first in first out fashion.
IdGenerator	Default `crate::trace::IdGenerator` implementation. Generates Trace and Span ids using a random number generator.
SamplingResult	The result of sampling logic for a given `Span`.
SimpleSpanProcessor	A `SpanProcessor` that exports synchronously when spans are finished.
Span	Single operation within a trace.
SpanLimits	Span limit configuration to keep attributes, events and links to a span in a reasonable number.
Tracer	`Tracer` implementation to create and manage spans
TracerProvider	Creator and registry of named `Tracer` instances.
XrayIdGenerator	Generates AWS X-Ray compliant Trace and Span ids.

BatchMessage	Messages sent between application thread and batch span processor’s work thread.
Sampler	Sampling options
SamplingDecision	Decision about whether or not to sample

ShouldSample	The `ShouldSample` interface allows implementations to provide samplers which will return a sampling `SamplingResult` based on information that is typically available just before the `Span` was created.
SpanProcessor	`SpanProcessor` is an interface which allows hooks for span start and end method invocations. The span processors are invoked only when is_recording is true.
TraceRuntime	Trace runtime is an extension to `Runtime`. Currently it provides a channel that used by `BatchSpanProcessor`.
TrySend	TrySend is an abstraction of sender that is capable to send BatchMessage with reference.
