Struct memory_structs::Page

pub struct Page { /* private fields */ }

A Page is a chunk of virtual memory aligned to a [PAGE_SIZE] boundary.

Implementations

impl Page

pub const fn start_address(&self) -> VirtualAddress

Returns the VirtualAddress at the start of this Page.

pub const fn number(&self) -> usize

Returns the number of this Page.

pub const fn containing_address(addr: VirtualAddress) -> Page

Returns the Page containing the given VirtualAddress.

impl Page

pub const fn p4_index(&self) -> usize

Returns the 9-bit part of this Page’s VirtualAddress that is the index into the P4 page table entries list.

pub const fn p3_index(&self) -> usize

Returns the 9-bit part of this Page’s VirtualAddress that is the index into the P3 page table entries list.

pub const fn p2_index(&self) -> usize

Returns the 9-bit part of this Page’s VirtualAddress that is the index into the P2 page table entries list.

pub const fn p1_index(&self) -> usize

Returns the 9-bit part of this Page’s VirtualAddress that is the index into the P1 page table entries list.

Using this returned usize value as an index into the P1 entries list will give you the final PTE, from which you can extract the mapped Frame using PageTableEntry::pointed_frame().

Trait Implementations

impl Add<usize> for Page

type Output = Page

The resulting type after applying the + operator.

fn add(self, rhs: usize) -> Page

Performs the + operation.

impl AddAssign<usize> for Page

fn add_assign(&mut self, rhs: usize)

Performs the += operation.

impl Clone for Page

fn clone(&self) -> Page

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Page

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

Formats the value using the given formatter.

impl Ord for Page

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Page> for Page

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<Page> for Page

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Step for Page

Implementing Step allows Page to be used in an Iterator.

🔬This is a nightly-only experimental API. (step_trait)

Returns the number of successor steps required to get from start to end.

fn forward_checked(start: Page, count: usize) -> Option<Page>

🔬This is a nightly-only experimental API. (step_trait)

Returns the value that would be obtained by taking the successor of self count times.
