HeapPageStateCache

Struct HeapPageStateCache 

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

A cache object that keeps track of the page states.

This cache has to be kept around and passed to every api call to the same memory region until the cache gets discarded.

Valid usecase:
Create cache 1 -> use 1 -> use 1 -> create cache 2 -> use 2 -> use 2

Invalid usecase:
Create cache 1 -> use 1 -> create cache 2 -> use 2 -> ❌ use 1 ❌

Make sure the page count is correct. If the number is lower than the actual amount, the code will panic at some point.
