Hi,
The following issue is solved when I enable the specialization
gated attribute:
impl<T> MyTrait for Vec<T>
where
T: Copy + Sized + Send + Sync + ... <- other non relevant traits for the question
{}
But with min_specialization
it fails, stating that
error: cannot specialize on trait `std::clone::Clone`
error: cannot specialize on trait `std::marker::Send`
error: cannot specialize on trait `std::marker::Sync`
So, now, using nightly, what are the real risks for my code to keep using the specialization
attr?
I tried with many variants and they all work as expected with the full specialization attribute.
I tried with trait specialization attributes to reduce the cope of specialization, but apparently it didn't make it.
with
#![feature(min_specialization)]
#![feature(rustc_attrs)]
in my lib.rs
and
#[rustc_specialization_trait]
impl<T> MyTrait for Vec<T>
where
T: Copy + Sized + Send + Sync + ... <- other non relevant traits for the question
{}
the issue remains.
Thanks!
