New creates and returns a WavefrontTracer which defers completed Spans to the given `reporter`.

NewInMemoryReporter creates new InMemorySpanReporter.

WithSampler defines a Sampler.

Delegator is the format to use for DelegatingCarrier.

DurationSampler allows spans above a given duration in milliseconds to be reported.

InMemorySpanReporter is a simple thread-safe implementation of SpanReporter that stores all reported spans in memory, accessible via reporter.getSpans().

NeverSample basic sampler to not sample any Spans.

RateSampler allows spans based on a rate.

RawSpan holds the span information.

SpanContext holds the basic Span metadata.

WavefrontTracer implements the OpenTracing `Tracer` interface.

DelegatingCarrier is a flexible carrier interface which can be implemented by types which have a means of storing the trace metadata and already know how to serialize themselves (for example, protocol buffers).

Sampler controls whether a span should be sampled/reported.

SpanReporter reports completed Spans.

CountingReporter it is primarily intended for testing purposes.

Option allows customizing the WavefrontTracer.
