Codegen

Provides an builder API to assist in generating Rust code.

More information about this crate can be found in the crate documentation

Installation

To use codegen, first add this to your Cargo.toml:

[dependencies]
codegen = { git = "https://github.com/carllerche/codegen" } # Soon on crates.io

Next, add this to your crate:

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:

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.
