Struct Trace 

pub struct Trace { /* private fields */ }

A live LLM trace that collects spans.

Traces use interior mutability via Mutex so that spans can add themselves to the trace without requiring exclusive (&mut) access. This enables the ergonomic pattern:

let trace = client.start_trace("chat");
let mut span = Span::new(&trace, SpanType::Generation, "llm");
span.end();  // adds to trace internally
trace.end();
