Derive Macro oy::InteractiveRoot

#[derive(InteractiveRoot)]

Derive this on a struct to make it an interactive access point for your application.

Same as #[derive(Interactive)] but with two additional impls:

• InteractiveRoot with its default methods
• Methods as a way to access free functions marked with the attribute Function (only available with default features on).

use oy::{Interactive, InteractiveRoot, Methods, Function};

#[derive(Interactive)]
struct SomethingInteractive;

#[Methods]
impl SomethingInteractive{
    fn ping(&self) -> &str{
        "pong"
    }
}

#[Function]
fn add_one(a: u32) -> u32 {
    a + 1
}

let something = SomethingInteractive;

#[derive(InteractiveRoot)]
struct Root {
    field: SomethingInteractive,
}

let mut root = Root { field: something };
assert_eq!(root.eval_to_string("field.ping()"), "\"pong\"");
assert_eq!(root.eval_to_string("add_one(42)"), "43");
