Implementations§

source§

impl BoundVar

source

pub const MAX_AS_U32: u32 = 4_294_967_040u32

Maximum value the index can take, as a u32.

source

pub const MAX: Self = _

Maximum value the index can take.

source

pub const ZERO: Self = _

Zero value of the index.

source

pub const fn from_usize(value: usize) -> Self

Creates a new index from a given usize.

§Panics

Will panic if value exceeds MAX.

source

pub const fn from_u32(value: u32) -> Self

Creates a new index from a given u32.

§Panics

Will panic if value exceeds MAX.

source

pub const fn from_u16(value: u16) -> Self

Creates a new index from a given u16.

§Panics

Will panic if value exceeds MAX.

source

pub 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.

source

pub const fn index(self) -> usize

Extracts the value of this index as a usize.

source

pub const fn as_u32(self) -> u32

Extracts the value of this index as a u32.

source

pub const fn as_usize(self) -> usize

Extracts the value of this index as a usize.
