Module 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. Use BatchConfigBuilder to configure your own instance of BatchConfig.
• BatchConfigBuilder
  A builder for creating BatchConfig instances.
• 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
• 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 passes finished spans to the configured SpanExporter, as soon as they are finished, without any batching. This is typically useful for debugging and testing. For scenarios requiring higher performance/throughput, consider using BatchSpanProcessor.
• Span
  Single operation within a trace.
• SpanEvents
  Stores span events along with dropped count.
• SpanLimits
  Span limit configuration to keep attributes, events and links to a span in a reasonable number.
• SpanLinks
  Stores span links along with dropped count.
• Tracer
  Tracer implementation to create and manage spans
• TracerProvider
  Creator and registry of named Tracer instances.

Enums

• 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.

Functions

• configDeprecated
  Default trace configuration
