- This is the result of running `cargo fix --edition`, with some manual adjustments. - The vast majority of changes merely qualify module paths with 'crate::'. - Two instances of adding an anonymous pattern to a trait's function. - `async` is a keyword in Rust 2018, and hence it needs to be escaped (e.g. in the case of the net::r#async module). - The manual adjustments were needed due to various shortcomings of the analysis employed by `cargo fix`, e.g. unexpanded macros, procedural macros, lalrpop grammars.
