Function try_cast_slice

pub fn try_cast_slice<A: NoUninit, B: CheckedBitPattern>(
    a: &[A],
) -> Result<&[B], CheckedCastError>

Try to convert &[A] into &[B] (possibly with a change in length).

• input.as_ptr() as usize == output.as_ptr() as usize
• input.len() * size_of::<A>() == output.len() * size_of::<B>()

Failure

• If the target type has a greater alignment requirement and the input slice isn’t aligned.
• If the target element type is a different size from the current element type, and the output slice wouldn’t be a whole number of elements when accounting for the size change (eg: 3 u16 values is 1.5 u32 values, so that’s a failure).
• If any element of the converted slice would contain an invalid bit pattern for B this fails.
