Enum PteType 

pub enum PteType {
    Page(usize),
    PageTable(usize),
}

The PTE can either be a page or page table.

Variants

Page(usize)

The PTE refers to a physical page.

PageTable(usize)

The PTE refers to another page table.

Implementations

impl PteType

pub fn is_page(&self) -> bool

Returns true if the PteType is a page and false otherwise.

pub fn is_page_table(&self) -> bool

Returns true if the PteType is a page table and false otherwise.

pub fn level(&self) -> usize

Extracts the level at which the PTE is found. The level is a monotonicly increasing number that starts at zero for the leaf page table and where the maximum number is the root page table.

pub fn is_huge_page(&self) -> bool

Returns whether the current PTE refers to a huge page, i.e. it checks whether the page type is a page and the level is non-zero. Returns true if it is a huge page and false otherwise.

Trait Implementations

impl Clone for PteType

fn clone(&self) -> PteType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PteType

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

Formats the value using the given formatter.

impl PartialEq for PteType

fn eq(&self, other: &PteType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
