Implementations

impl VariantId

pub const MAX_INDEX: usize = 4_294_967_295usize

If Self::CHECKS_MAX_INDEX is true, we’ll assert if trying to produce a value larger than this in any of the ctors that don’t have unchecked in their name.

pub const CHECKS_MAX_INDEX: bool = true

Does this index type assert if asked to construct an index larger than MAX_INDEX?

const _ENSURE_RAW_IS_UNSIGNED: [(); 0] = _

pub fn new(value: usize) -> Self

pub fn from_raw(value: usize) -> Self

Construct this index type from the wrapped integer type.

pub fn from_foreign<F: Idx>(value: F) -> Self

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

Construct from a usize without any checks.

pub const fn from_raw_unchecked(raw: usize) -> Self

Construct from the underlying type without any checks.

pub fn from_usize(value: usize) -> Self

pub const fn raw(self) -> usize
