pub fn propagate_scope_to_thread() -> Result<ScopeStackHandle>Expand description
Capture the current scope stack handle for use in another thread.
This returns the handle currently visible to the caller so it can be passed
into set_thread_scope_stack elsewhere.
§Returns
A Result containing the active ScopeStackHandle.
§Errors
Returns an error when the current context does not yet own an active scope stack.
§Notes
The returned handle is shared; it does not clone the underlying stack.
