Struct PageTableIndex

pub struct PageTableIndex(/* private fields */);

A 9-bit index into a page table.

Can be used to select one of the 512 entries of a page table.

Guaranteed to only ever contain 0..512.

Implementations

impl PageTableIndex

pub const fn new(index: u16) -> Self

Creates a new index from the given u16. Panics if the given value is >=512.

pub const fn new_truncate(index: u16) -> Self

Creates a new index from the given u16. Throws away bits if the value is >=512.

Trait Implementations

fn from(index: PageTableIndex) -> Self

Converts to this type from the input type.

impl From<PageTableIndex> for u64

fn from(index: PageTableIndex) -> Self

Converts to this type from the input type.

impl From<PageTableIndex> for usize

fn from(index: PageTableIndex) -> Self

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl Index<PageTableIndex> for PageTable

type Output = PageTableEntry

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl IndexMut<PageTableIndex> for PageTable

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

Performs the mutable indexing (container[index]) operation.

impl Ord for PageTableIndex

fn cmp(&self, other: &PageTableIndex) -> 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 PageTableIndex

fn eq(&self, other: &PageTableIndex) -> 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 PageTableIndex

fn partial_cmp(&self, other: &PageTableIndex) -> 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.

impl Step for PageTableIndex

fn steps_between(start: &Self, end: &Self) -> Option<usize>

🔬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: Self, count: usize) -> Option<Self>

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