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 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.

Statics

TASK_SCOPE_STACK

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

capture_thread_scope_stack

Capture the current thread-local scope stack binding.

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

Restore a previously captured thread-local scope stack binding.

scope_stack_active

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

set_thread_scope_stack

sync_thread_scope_stack

Synchronize the thread-local scope stack without marking it explicit.

task_scope_push

Push a scope handle onto the active stack.

task_scope_remove
