Upgrading from 0.7 to 0.8: Ref::new_slice gone?

[ChristopherRabotin]

Hi there,

After reading through the upgrading guide in the announcement and searching in the docs, I can't seem to find a method equivalent to 0.7's Ref::new_slice. Using the new from_bytes seems like it should work at first thought, but there is no way to convert the underlying bytes into a slice of type T, like I've done here:

// (...)
        Ok(match Ref::new_slice(&rcrd_bytes[SummaryRecord::SIZE..]) {
            Some(data) => data.into_slice(),
            None => &{
                R::default();
                [] as [R; 0]
            },
        })

Has this functionality been moved to another struct, or has it been removed entirely?

Thanks

Given a Ref<[T]>, both Ref::from_bytes and Ref::into_ref will work as expected - you no longer need to special-case slices either during construction or when converting to a vanilla reference.

Thanks!

The following should be the equivalent in version 0.8:

        Ok(
            match Ref::<_, [R]>::from_bytes(&rcrd_bytes[SummaryRecord::SIZE..]) {
                Ok(r) => Ref::into_ref(r),
                Err(_) => &{
                    R::default();
                    [] as [R; 0]
                },
            },
        )
