Rust code generation library

codegen-rs

This is a work-in-progress code generation library for Rust.

The exact way to create code is not set in stone yet and there are still several things missing.

Feel free to open an issue if you have any ideas for the library.

Generation currently looks like this:

let mut module = Module::new(); // Create a new module

let s_vec2 = module.add_struct("Vec2").set_public(true); // Create a struct
s_vec2.add_field("x", "f32").set_public(true);
s_vec2.add_field("y", "f32").set_public(true);

let i_vec2 = module.add_impl("Vec2"); // Create an impl block
let vec2_new = i_vec2 // Create a function in the impl block
    .add_function("new")
    .set_public(true)
    .set_const(true)
    .add_param("x", "f32")
    .add_param("y", "f32")
    .set_return_type("Self");

vec2_new
    .add_body()
    .add_statement(Statement::Return(Box::new(ReturnStatement::new(
        expr::init_struct("Self")
            .field_auto("x")
            .field_auto("y")
            .into(),
    )))); // Add a body to the function

let code = module.to_string();

The above will generate this code:

pub struct Vec2 {
    pub x: f32,
    pub y: f32,
}

impl Vec2 {
    pub const fn new(x: f32, y: f32) -> Self {
        return Self { x, y };
    }
}
