Struct PageOffset

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

A 12-bit offset into a 4KiB Page.

This type is returned by the VirtAddr::page_offset method.

Guaranteed to only ever contain 0..4096.

Implementations

impl PageOffset

pub fn new(offset: u16) -> Self

Creates a new offset from the given u16. Panics if the passed value is >=4096.

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

Creates a new offset from the given u16. Throws away bits if the value is >=4096.

Trait Implementations

impl Clone for PageOffset

fn clone(&self) -> PageOffset

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PageOffset

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

Formats the value using the given formatter.

impl From<PageOffset> for u16

fn from(offset: PageOffset) -> Self

Converts to this type from the input type.

impl From<PageOffset> for u32

fn from(offset: PageOffset) -> Self

Converts to this type from the input type.

impl From<PageOffset> for u64

fn from(offset: PageOffset) -> Self

Converts to this type from the input type.

impl From<PageOffset> for usize

fn from(offset: PageOffset) -> Self

Converts to this type from the input type.

impl Hash for PageOffset

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

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 PageOffset

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

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

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