Struct TraceContext 

#[non_exhaustive]
pub struct TraceContext {
    pub traceparent: Option<String>,
    pub tracestate: Option<String>,
}

W3C Trace Context, carried verbatim. Reliar never invents or re-derives it (ADR 0004, ADR 0020): a transport mapper writes these from an active span and reads them back on decode.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

traceparent: Option<String>

The W3C traceparent header value.

tracestate: Option<String>

The W3C tracestate header value.
