Nesting

Nesting is a Rust proc-macro library for defining structs, enums, and impls in a nested fashion.

Ideal for writing configs or heavily-nested data structures.

Installation

$ cargo add nesting

Example

nesting::nest! {
	#![derive(Debug)]

    struct MyStruct {
        child: MyChildStruct

        struct MyChildStruct {
            is_nested: bool,

            impl Default for MyChildStruct {
                fn default() -> Self {
                    Self { is_nested: true}
                }
            }
        }
    }
}

fn main() {
	let x = MyStruct {
		child: MyChildStruct::default(),
	};

	dbg!(&x);
}
