Struct L4Index 

#[repr(transparent)]
pub struct L4Index(u16);

Index into the PML4 table (derived from virtual-address bits [47:39]).

This newtype prevents accidental mixing with other indices and allows compile-time checking of valid index ranges (0..512).

Tuple Fields

0: u16

Implementations

impl L4Index

pub const fn from(va: VirtualAddress) -> Self

Construct an index from a canonical virtual address by extracting bits [47:39].

Returns a value in 0..512.

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

Construct an index from a raw u16.

Panics / Debug assertions

• Debug builds assert v < 512.

pub const fn as_usize(self) -> usize

Return the index as usize for array indexing.

Trait Implementations

impl Clone for L4Index

fn clone(&self) -> L4Index

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hash for L4Index

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 L4Index

fn cmp(&self, other: &L4Index) -> 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 L4Index

fn eq(&self, other: &L4Index) -> 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 L4Index

fn partial_cmp(&self, other: &L4Index) -> 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.
