Struct MaxHeapPayload 

#[repr(C)]
pub struct MaxHeapPayload {
    pub element_descriptor: *const TypeDescriptor,
    pub items: BinaryHeap<HeapEntry>,
}

The MaxHeap[T] payload (§11.2): a max-heap of HeapEntry.

Fields

element_descriptor: *const TypeDescriptor

The descriptor for every element, or null when the construction site had no static element type. A label: each element carries its own descriptor, both on its HeapEntry and in its object header. Read it through MaxHeapPayload::element.

items: BinaryHeap<HeapEntry>

The elements, in max-heap order (largest surfaces first).

Implementations

impl MaxHeapPayload

pub fn element(&self) -> Option<&'static TypeDescriptor>

The element label, or None when this heap was never told its element type.
