Function extractSpan

extractSpan<T extends Record<string, unknown>>(
    params: T,
): {
    context: Context;
    params: Omit<T, "traceparent" | "tracestate" | "baggage">;
    span: Span | undefined;
}
Extract a Span from workflow params using the globally registered textmap propagator.

This is a convenience wrapper around extractContext that also retrieves the remote span from the extracted context via trace.getSpan(). The returned span is a non-recording remote span suitable for use as a parent option in withTrace or trace.setSpan().
Type Parameters
- T extends Record<string, unknown>
Parameters
- params: T
  The params object containing propagation headers.
Returns {
    context: Context;
    params: Omit<T, "traceparent" | "tracestate" | "baggage">;
    span: Span | undefined;
}
An object with the extracted span (if any), context, and cleaned params.
Example
```
const { params: clean, span: parentSpan } = extractSpan(event.payload);
await withTrace(
  async (span) => { ... },
  { parent: parentSpan, name: "child-operation" },
);
```
