pub fn indexes(&self) -> [usize; 3]

Return VPN 3 level index

Trait Implementations

impl Clone for VirtPageNum

fn clone(&self) -> VirtPageNum

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VirtPageNum

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

Formats the value using the given formatter.

impl From<VirtAddr> for VirtPageNum

fn from(v: VirtAddr) -> Self

Converts to this type from the input type.

impl From<VirtPageNum> for VirtAddr

fn from(v: VirtPageNum) -> Self

Converts to this type from the input type.

impl From<VirtPageNum> for usize

fn from(v: VirtPageNum) -> Self

Converts to this type from the input type.

impl From<usize> for VirtPageNum

fn from(v: usize) -> Self

Converts to this type from the input type.

impl Ord for VirtPageNum

fn cmp(&self, other: &VirtPageNum) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for VirtPageNum

fn eq(&self, other: &VirtPageNum) -> 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 for VirtPageNum

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