+/// Construct a TelemetryLayer that publishes telemetry to honeycomb.io using the
+/// provided honeycomb config, and sample rate. This function differs from
+/// `new_honeycomb_telemetry_layer` and the `sample_rate` on the
+/// `libhoney::Config` there in an important way. `libhoney` samples `Event`
+/// data, which is individual spans on each trace. This means that using the
+/// sampling logic in libhoney may result in missing event data or incomplete
+/// traces. Calling this function provides trace-level sampling, meaning sampling
+/// decisions are based on a modulo of the traceID, and events in a single trace
+/// will not be sampled differently. If the trace is sampled, then all spans
+/// under it will be sent to honeycomb. If a trace is not sampled, no spans or
+/// events under it will be sent. When using this trace-level sampling, the
+/// `sample_rate` parameter on the `libhoney::Config` should be set to 1, which
+/// is the default.
+///
+/// Specialized to the honeycomb.io-specific SpanId and TraceId provided by this crate.
