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.
RandomIdGenerator
Default IdGenerator implementation.
SimpleSpanProcessor
A SpanProcessor that passes finished spans to the configured SpanExporter, as soon as they are finished, without any batching.
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
Default Sampling options

IdGenerator
Interface for generating IDs
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.
