Function constmuck::cast_slice_alt

pub const fn cast_slice_alt<T, U>(
    from: &[T], 
    bounds: (IsPod<T>, IsPod<U>)
) -> &[U]

Casts &[T] to &[U]

Requires both T and U to implement Pod.

Difference with bytemuck

This function has the same differences with bytemuck::cast_slice that try_cast_slice_alt does with bytemuck::try_cast_slice.

Example

use constmuck::PodCastError;
use constmuck::{cast_slice_alt, infer};

type Res<T> = Result<T, PodCastError>;

const I8S: &[i8] = cast_slice_alt(&[100u8, 254, 255], infer!());

assert_eq!(*I8S, [100, -2, -1]);
