TracingComposer

Utilities for composing multiple tracers.

Provides functional composition patterns for combining, filtering, and transforming trace events across multiple tracing backends.

== Combining Tracers ==

Send events to multiple backends simultaneously:

val combined = TracingComposer.combine(consoleTracer, langfuseTracer)
combined.traceEvent(event) // Sends to both

== Filtering Events ==

Only trace events matching a predicate:

val errorsOnly = TracingComposer.filter(tracer)(_.eventType == "error_occurred")

== Transforming Events ==

Modify events before tracing:

val enriched = TracingComposer.transform(tracer) {
 case e: TraceEvent.CustomEvent => e.copy(name = "prefix_" + e.name)
 case other => other
}
