Methods

impl<S: PageSize> Page<S>

pub fn from_start_address(address: VirtAddr) -> Result<Self, ()>

Returns the page that starts at the given virtual address.

Returns an error if the address is not correctly aligned (i.e. is not a valid page start).

pub fn containing_address(address: VirtAddr) -> Self

Returns the page that contains the given virtual address.

pub fn start_address(&self) -> VirtAddr

Returns the start address of the page.

pub const fn size(&self) -> u64

Returns the size the page (4KB, 2MB or 1GB).

pub fn p4_index(&self) -> u9

Returns the level 4 page table index of this page.

pub fn p3_index(&self) -> u9

Returns the level 3 page table index of this page.
