`rustc_data_structures::thin_vec::ThinVec` looks like this: ``` pub struct ThinVec<T>(Option<Box<Vec<T>>>); ``` It's just a zero word if the vector is empty, but requires two allocations if it is non-empty. So it's only usable in cases where the vector is empty most of the time. This commit removes it in favour of `thin_vec::ThinVec`, which is also word-sized, but stores the length and capacity in the same allocation as the elements. It's good in a wider variety of situation, e.g. in enum variants where the vector is usually/always non-empty. The commit also: - Sorts some `Cargo.toml` dependency lists, to make additions easier. - Sorts some `use` item lists, to make additions easier. - Changes `clean_trait_ref_with_bindings` to take a `ThinVec<TypeBinding>` rather than a `&[TypeBinding]`, because this avoid some unnecessary allocations.
