Trace-context
TraceContext carries the standard log fields used to correlate records with distributed traces: trace_id, span_id, trace_flags, and optional trace_state.

let context = trace_context(
"4bf92f3577b34da6a3ce929d0e0e4736",
"00f067aa0ba902b7",
trace_state="vendor=value",
)Use context.as_fields() when integrating with a custom carrier, or pass the value to a logger's with_trace_context(...) helper. BitLogger does not parse HTTP headers or export OTLP data; an application-owned tracing library remains responsible for propagation and sampling.
