Implementations

impl Block

pub(crate) const MAX_INDEX: usize

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.

Create an index from a raw u32 without bounds checking.

Safety

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

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.
