Type Definition swim_mem::lease::PtrBox

type PtrBox<'a, T, M = ()> = Ptr<'a, Box<T, M>>;

[−] Expand description

Exclusive reference to a value stored in a Hold-allocated memory block, with optional metadata stored inside the allocation.

Storing metadata in the memory block keeps the pointer structure exactly the size of a pointer.

Examples

Move a value from the stack to the global hold by creating a PtrBox:

let value = 5;
let boxed = PtrBox::new(value);

Move a value from a PtrBox back to the stack by dereferencing:

let boxed = PtrBox::new(5);
let value = *boxed;
