187## Import Style

189Items from `hir` and `ast` should be used qualified:
190
191```rust
192// Good
193use ra_syntax::ast;
194
195fn frobnicate(func: hir::Function, strukt: ast::StructDef) {}
196
197// Not as good
198use hir::Function;
199use ra_syntax::ast::StructDef;
200
201fn frobnicate(func: Function, strukt: StructDef) {}
202```
203
204Avoid local `use MyEnum::*` imports.
205
206Prefer `use crate::foo::bar` to `use super::bar`.
