Tracing core rexport and utilities, for your conveneince

Modules§

callsite: Callsites represent the source locations from which spans or events originate.
dispatcher: Dispatches trace events to Subscribers.
event: Events represent single points in time during the execution of a program.
field: Span and Event key-value data.
instrument: Attach a span to a std::future::Future.
level_filters: Trace verbosity level filtering.
metadata: Metadata describing trace data.
subscriber: Collects and records trace data.

debug: Constructs an event at the debug level.
enabled: Checks whether a span or event is enabled based on the provided metadata.
error: Constructs an event at the error level.
error_span: Constructs a span at the error level.
event: Constructs a new Event.
event_enabled: Tests whether an event with the specified level and target would be enabled.
info: Constructs an event at the info level.
metadata: Statically constructs new span metadata.
span_enabled: Tests whether a span with the specified level and target would be enabled.
trace: Constructs an event at the trace level.
warn: Constructs an event at the warn level.
warn_span: Constructs a span at the warn level.

Dispatch: Dispatch trace data to a Subscriber.
Event: Events represent single points in time where something occurred during the execution of a program.
Id: Identifies a span within the context of a subscriber.
Level: Describes the level of verbosity of a span or event.
Metadata: Metadata describing a span or event.
MetricsLayer: A layer that publishes metrics via the OpenTelemetry SDK.
OpenTelemetryLayer: An OpenTelemetry propagation layer for use in a project that uses tracing.
OtelData: Per-span OpenTelemetry data tracked by this crate.
Span: A handle representing a span, with the capability to enter the span if it exists.

Callsite: Trait implemented by callsites.
Instrument: Attaches spans to a std::future::Future.
OpenTelemetrySpanExt: Utility functions to allow tracing Spans to accept and return OpenTelemetry Contexts.
PreSampledTracer: An interface for authors of OpenTelemetry SDKs to build pre-sampled tracers.
Subscriber: Trait representing the functions required to collect trace data.
Value: A field value of an erased type.

instrument: Instruments a function to create and enter a tracing span every time the function is called.
