Struct ash::util::Align

pub struct Align<T> {
    ptr: *mut c_void,
    elem_size: DeviceSize,
    size: DeviceSize,
    _m: PhantomData<T>,
}

Align handles dynamic alignment. The is useful for dynamic uniform buffers where the alignment might be different. For example a 4x4 f32 matrix has a size of 64 bytes but the min alignment for a dynamic uniform buffer might be 256 bytes. A slice of &[Mat4x4<f32>] has a memory layout of [[64 bytes], [64 bytes], [64 bytes]], but it might need to have a memory layout of [[256 bytes], [256 bytes], [256 bytes]]. Align::copy_from_slice will copy a slice of &[T] directly into the host memory without an additional allocation and with the correct alignment.
