pub fn extract_context(ctx: &ActorContext) -> Option<ContextSnapshot>Expand description
Extract the propagated context snapshot from actor message headers.
Checks for a ContextSnapshotHeader (local hop) first, then falls
back to ContextHeader (remote wire bytes). Returns None if no
propagated context is present.
Useful for advanced scenarios such as spawning sub-tasks that need the propagated context, or inspecting context values without relying on the task-local scope.
