First off, this is awesome! I definitely think the code is cleaner this way, and I love the work you put into the comments making the algorithm clear. Second, I'm sorry for the delay in having this reviewed -- it seems to've fallen through the cracks. In the future, feel free to ping me or any other member of the team by leaving an "r? @aturon" comment or messaging on IRC if your PR goes unreviewed for more than a day or two. Meantime, I'm handing this off to bors. Nice work! |

Additionally, support zero-sized types. Now there isn't a safe interface of `PartialVec` anymore, it's just a bare data structure with destructor that assumes you handled everything correctly before.

fix: ensure that the parent of a SourceRoot cannot be itself fix rust-lang#17378. In `FileSetConfig.map`, different roots might be mapped to the same `root_id` due to deduplication in `ProjectFolders::new`: ```rust // Example from rustup /Users/roife/code/rustup/target/debug/build/rustup-863a063426b56c51/out /Users/roife/code/rustup ``` In `source_root_parent_map`, r-a might encounter paths where their SourceRootId (i.e. `root_id`) is identical, yet one the them is the parent of the another. This situation can cause the `root_id` to be its own parent, potentially leading to an infinite loop. This PR resolves such cases by adding a check.
