    Very basic sampling strategy which allows for sampling N requests within a fixed time window.
    MonotonicNanoClock
    Clock which returns a monotonically increasing timestamp from an undefined epoch.
    ProbabilisticSampleRate
    Simple implementation of OpenCensus algorithm for probabilistic rate limiting as outlined in https://github.com/census-instrumentation/opencensus-specs/blob/master/trace/Sampling.md
    SamplingStrategy

    SamplingTraceExporter
    Trace exporter which only exports a subset of traces as decided by the provided sampling strategy.
    TraceDescription
    High-level description of a trace and the actual trace itself.
    TraceExporter
    Potentially exports a trace to an underlying consumer.
