"""Convenient helpers for creating spans / traces.

All emitters operate in two modes, switchable via the `propagate` parameter.
The emitters first [`SpanCreationRequest`][agentlightning.SpanCreationRequest] object, then:

1. When `propagate` is True, this creation request will be propagated to the active tracer
   and a [`Span`][agentlightning.Span] instance will be created (possibly deferred).
2. When `propagate` is False, the creation request will be returned directly. Useful for cases
   when you don't have a tracer but you want to create a creation request for later use.
