Function alloc_aligned_custom 

pub fn alloc_aligned_custom<T>(size: usize, align: usize) -> Vec<T>

Allocates a zero-initialized Vec<T> with custom alignment.

The total byte size (size * size_of::<T>()) must be a multiple of align, and align must be a power of two.

Panics

• If T is zero-sized.
• If align is not a power of two.
• If size * size_of::<T>() is not a multiple of align.
