Function scope_stack_active 

pub fn scope_stack_active() -> bool

Report whether the current context has an explicitly active scope stack.

This checks task-local state first and otherwise falls back to the thread-local explicit flag.

Returns

true when the current async task or thread already owns an active scope stack and false otherwise.

Notes

A synchronized thread-local stack does not count as explicit unless it was installed through set_thread_scope_stack.
