Struct ValueIndex

struct ValueIndex {
    private_use_as_methods_instead: u32,
}

This index uniquely identifies a tracked place and therefore a slot in State.

It is an implementation detail of this module.

Fields

private_use_as_methods_instead: u32

Implementations

impl ValueIndex

const MAX_AS_U32: u32 = 4_294_967_040u32

Maximum value the index can take, as a u32.

const MAX: Self = _

Maximum value the index can take.

const ZERO: Self = _

Zero value of the index.

const fn from_usize(value: usize) -> Self

Creates a new index from a given usize.

Panics

Will panic if value exceeds MAX.

const fn from_u32(value: u32) -> Self

Creates a new index from a given u32.

Panics

Will panic if value exceeds MAX.

const fn from_u16(value: u16) -> Self

Creates a new index from a given u16.

Panics

Will panic if value exceeds MAX.

const unsafe fn from_u32_unchecked(value: u32) -> Self

Creates a new index from a given u32.

Safety

The provided value must be less than or equal to the maximum value for the newtype. Providing a value outside this range is undefined due to layout restrictions.

Prefer using from_u32.

const fn index(self) -> usize

Extracts the value of this index as a usize.

const fn as_u32(self) -> u32

Extracts the value of this index as a u32.

const fn as_usize(self) -> usize

Extracts the value of this index as a usize.

Trait Implementations

impl Add<usize> for ValueIndex

type Output = ValueIndex

The resulting type after applying the + operator.

fn add(self, other: usize) -> Self

Performs the + operation.

impl Clone for ValueIndex

fn clone(&self) -> ValueIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueIndex

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

Formats the value using the given formatter.

impl From<ValueIndex> for u32

fn from(v: ValueIndex) -> u32

Converts to this type from the input type.

impl From<ValueIndex> for usize

fn from(v: ValueIndex) -> usize

Converts to this type from the input type.

impl From<u32> for ValueIndex

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<usize> for ValueIndex

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Hash for ValueIndex

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,

impl Idx for ValueIndex

fn new(value: usize) -> Self

fn index(self) -> usize

fn increment_by(&mut self, amount: usize)

fn plus(self, amount: usize) -> Self

impl PartialEq for ValueIndex

fn eq(&self, other: &ValueIndex) -> 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.
