Struct Inst 

pub(crate) struct Inst(NonMaxU32);

0: NonMaxU32

Implementations

impl Inst

pub(crate) const MAX_INDEX: usize

The maximum representable index value.

pub(crate) const CHECKS_MAX_INDEX: bool = true

Whether this index type performs bounds checking.

pub(crate) const fn new(value: usize) -> Self

Create a new index from a usize value.

Panics

Panics if value > MAX_INDEX.

pub(crate) const fn from_raw(value: NonMaxU32) -> Self

Create an index from a raw NonMaxU32 value.

Convert an index from another index type.

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

Safety

The caller must ensure value <= MAX_INDEX.

pub(crate) const fn from_raw_unchecked(raw: u32) -> Self

Create an index from a raw u32 without bounds checking.

Safety

The caller must ensure the value is not u32::MAX.

Panics

Panics if value > MAX_INDEX.

pub(crate) const fn index(self) -> usize

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
