Struct HeapGuard 

pub struct HeapGuard { /* private fields */ }

A scoped guard for the currently-active heap. Pushed at entry to state.run() / state.protected_call() / state.load(); popped on drop. Supports nesting (multiple LuaStates on one thread).

Implementations

impl HeapGuard

pub fn push(heap: &Heap) -> Self

Push heap onto the active stack. Returns a guard; dropping it pops.

Safety

The pointer must remain valid for the lifetime of the guard. Callers typically pass &state.global.heap, which lives as long as the GlobalState (an Rc<RefCell<_>>); the guard must drop before the state is dropped.

Trait Implementations

impl Drop for HeapGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
