Function gvariant::aligned_bytes::align_offset

pub fn align_offset<A: Alignment>(idx: usize) -> AlignedOffset<A>

Construct an AlignedOffset by rounding-up idx until it's a multiple of A::ALIGNMENT.

This is useful for GVariant deserialisation because often we have an offset representing the end of a value and we want to find the start of the next one. This involves padding according to the next value's alignment.
