Struct x86_64::structures::paging::page_table::PageTable

#[repr(C, align(4096))]
pub struct PageTable { /* private fields */ }

Represents a page table.

Always page-sized.

This struct implements the Index and IndexMut traits, so the entries can be accessed through index operations. For example, page_table[15] returns the 16th page table entry.

Note that while this type implements [Clone], the users must be careful not to introduce mutable aliasing by using the cloned page tables.

Implementations

impl PageTable

pub const fn new() -> Self

Creates an empty page table.

pub fn zero(&mut self)

Clears all entries.

pub fn iter(&self) -> impl Iterator<Item = &PageTableEntry>

Returns an iterator over the entries of the page table.

pub fn iter_mut(&mut self) -> impl Iterator<Item = &mut PageTableEntry>

Returns an iterator that allows modifying the entries of the page table.

pub fn is_empty(&self) -> bool

Checks if the page table is empty (all entries are zero).

Trait Implementations

impl Debug for PageTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PageTable

fn default() -> Self

Returns the “default value” for a type.

impl Index<PageTableIndex> for PageTable

type Output = PageTableEntry

The returned type after indexing.

fn index(&self, index: PageTableIndex) -> &Self::Output
