Struct 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
