Module scope_stack 

Scope stack storage and propagation helpers.

The runtime tracks the current scope hierarchy through a shared ScopeStack stored in task-local or thread-local state. Advanced callers can use this module to inspect the active scope chain, attach scope-local middleware, or propagate scope context into worker threads.

Structs

ScopeStack

Mutable stack of active scopes plus their scope-local registries.

ThreadScopeStackBinding

Captured thread-local scope stack binding.

Task-local scope stack handle used by async execution contexts.

create_scope_stack

Create a new scope stack handle with an implicit root scope.

current_scope_stack

Return the scope stack visible to the current execution context.

propagate_scope_to_thread

Capture the current scope stack handle for use in another thread.

restore_thread_scope_stack
