Crate rust_codegen

Provides a builder API for generating Rust code.

The general strategy for using the crate is as follows:

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 rust_codegen::Scope;

let mut scope = Scope::new();

scope.new_struct("Foo")
    .derive("Debug")
    .field("one", "usize")
    .field("two", "String");

println!("{}", scope.to_string());
