Function gvariant::casting::try_cast_slice_to

pub fn try_cast_slice_to<'a, T: AlignOf + AllBitPatternsValid>(
    s: &'a AlignedSlice<T::AlignOf>
) -> Result<&'a T, WrongSize>

Safely cast an &AlignedSlice to &T where T: Sized

If the length of the input slice isn't exactly the size of T this function will return Err(WrongSize).
