type Visitor = BlackholeVisitor

Type used to record tracing fields.

type TraceId = TraceId

Globally unique identifier, uniquely identifies a trace.

type SpanId = SpanId

Identifies spans within a trace.

fn mk_visitor(&self) -> Self::Visitor

Initialize a visitor, used to record values from spans and events as they are observed

fn report_span(&self, _: Span<Self::Visitor, Self::SpanId, Self::TraceId>)

Report a Span to this Telemetry instance’s backend.

fn report_event(&self, _: Event<Self::Visitor, Self::SpanId, Self::TraceId>)

Report an Event to this Telemetry instance’s backend.
