Enum PageTableLevel

#[repr(u8)]
pub enum PageTableLevel {
    Pt = 0,
    Pd = 1,
    Pdpt = 2,
    Pml4 = 3,
}

Available on crate feature arch-amd64 only.

The levels in the page table hierarchy.

Variants

Pt = 0

Page Table (PT) - the lowest level, pointing directly to 4KB pages.

Pd = 1

Page Directory (PD) - can point to PTs or 2MB large pages.

Pdpt = 2

Page Directory Pointer Table (PDPT) - can point to PDs or 1GB large. pages

Pml4 = 3

Page Map Level 4 (PML4) - the highest level in 4-level paging.

Implementations

impl PageTableLevel

pub fn next(self) -> Option<PageTableLevel>

Returns the next lower level in the page table hierarchy.

pub fn previous(self) -> Option<PageTableLevel>

Returns the next higher level in the page table hierarchy.

Trait Implementations

impl Clone for PageTableLevel

fn clone(&self) -> PageTableLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PageTableLevel

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

Formats the value using the given formatter.

impl Hash for PageTableLevel

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PageTableLevel

fn cmp(&self, other: &PageTableLevel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PageTableLevel

fn eq(&self, other: &PageTableLevel) -> 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.

impl PartialOrd for PageTableLevel

fn partial_cmp(&self, other: &PageTableLevel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
