 We define constants for the page size, the size of an entry in a page table, and the number of entries per table. To make future function signatures more expressive, we can use the type aliases `PhysicalAddress` and `VirtualAddress`. The `Page` struct is similar to the `Frame` struct in the [previous post], but represents a virtual page instead of a physical frame.
