Module opentelemetry_sdk::trace

Available 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.

Structs

• 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.
• JaegerRemoteSampler
  Sampler that fetches the sampling configuration from remotes.
• JaegerRemoteSamplerBuilder
  Builder for JaegerRemoteSampler. See Sampler::jaeger_remote for details.
• RandomIdGenerator
  Default IdGenerator implementation.
• 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.

Enums

• BatchMessage
  Messages sent between application thread and batch span processor’s work thread.
• Sampler
  Default Sampling options

Traits

• 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.
• 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.

Functions

• config
  Default trace configuration
