I noticed that the current implementation of `define!` and `extend!` macros are incompatible with `rustfmt`. Therefore, I propose the following new design: ```rust define!({ #[derive(Debug)] pub struct Text(String); adjust(|t| *t...
Right now, when value fails validation by `ensure` closure, the returned error is a static string `"value is invalid"`. It would be cool to support customisation of that string: ```rust...
Right now README file is generated using [`cargo-readme`](https://github.com/livioribeiro/cargo-readme), but this tool doesn't support intralinks and wasn't maintained for more than 2 years. [Link to `cargo-rdme`](https://crates.io/crates/cargo-rdme)
