RFC: Private trait items

[rust-highfive]

Tracking issue for postponed PR #52

We could use pub(restricted) for this, instead of reintroducing priv.

In particular, maybe we could use pub(impl) to restrict visibility to the "implementation" of the trait.

Closing in favor of #2028

@petrochenkov
As I understand it, your proposal is different, as it disallows implementing a private trait item.

This RFC is for trait items that can be implemented, but not visible to users.

[petrochenkov]

Hm, indeed, that RFC proposes something very different (I wouldn't call that "private trait items").

Hi, I just wanted to cross post my use case from #52 here so it can hopefully be given some attention.

Perhaps the RFC could be rewritten with some of the new ideas such as using pub(restricted) syntax instead of priv keyword or defaultly private methods?
