Struct PageGuard 

Source 
pub struct PageGuard { /* private fields */ }
Expand description

Keeps a page as it is for as long as it lives: nothing new is carved from it, it is never released, and relocation leaves everything on it in place.

What a graph holds on the memory it replays against. A graph keeps raw addresses but no bindings, so the bytes behind them must neither move nor be handed to another allocation. The allocations on the page keep their handles untouched, so one can still be updated in place while the page is guarded.

A resolved resource needs no guard: the binding it holds keeps its own allocation in place, and leaves the rest of the page to other allocations.
