Nesting is a procedural macro. It will run at compile time and transform your program's source code.

Adding `nesting` macro(s) as a dependency

Run this command in a terminal, in your project's directory:

cargo add nesting

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

nesting = "0.1.1"

You may need to import the macro(s) with use nesting::*.

Read the nesting documentation.

Readme

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);
}
