2023-10-17Remove `IdFunctor` trait.Nicholas Nethercote-116/+0
It's defined in `rustc_data_structures` but is only used in `rustc_type_ir`. The code is shorter and easier to read if we remove this layer of abstraction and just do the things directly where they are needed.

2023-02-14Refactor refcounted structural_impls via functorsAlan Egerton-1/+50
2022-06-08Use liballoc's specialised in-place vec collectionAlan Egerton-34/+2
liballoc already specialises in-place vector collection, so manually reimplementing it in `IdFunctor::try_map_id` was superfluous.

2021-12-03Rollup merge of #88906 - Kixunil:box-maybe-uninit-write, r=dtolnayMatthias Krüger-4/+2
Implement write() method for Box<MaybeUninit<T>> This adds method similar to `MaybeUninit::write` main difference being it returns owned `Box`. This can be used to elide copy from stack safely, however it's not currently tested that the optimization actually occurs. Analogous methods are not provided for `Rc` and `Arc` as those need to handle the possibility of sharing. Some version of them may be added in the future. This was discussed in #63291 which this change extends.
