# Codegen Provides an builder API to assist in generating Rust code. [](https://travis-ci.org/carllerche/codegen) More information about this crate can be found in the [crate documentation][dox] [dox]: https://docs.rs/codegen/0.1.3/codegen/ ## Installation To use `codegen`, first add this to your `Cargo.toml`: ```toml [dependencies] codegen = "0.1.3" ``` Next, add this to your crate: ```rust extern crate codegen; ``` ## Usage 1) Create a `Scope` instance. 2) Use the builder API to add elements to the scope. 3) Call `Scope::to_string()` to get the generated code. For example: ```rust use codegen::Scope; let mut scope = Scope::new(); scope.new_struct("Foo") .derive("Debug") .field("one", "usize") .field("two", "String"); println!("{}", scope.to_string()); ``` ## Non-goals `codegen` will not attempt to perform anything beyond basic formatting. For improved formatting, the generated code can be passed to `rustfmt`. ## License This project is licensed under the [MIT license](LICENSE). ### Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in `codegen` by you, shall be licensed as MIT, without any additional terms or conditions.
