Some suggestion

[chmnchiang]

1. Aren't Crossbeam and Rayon libraries about threads? They doesn't seem to match the description "Run external commands".

2. The python code of derive_new crate __init__(self, value='default') kind of suggest that rust has optional parameters, which rust does not.

1. I'll dig more into Crossbeam and Rayon and also try to find the external command runner equivalent, thanks

2. about derive_new, it offers default values for initializers just like in Python's __init__ method.

use std::marker::PhantomData;

#[derive(new)]
struct Generic<'a, T: Default, P> {
    x: &'a str,
    y: PhantomData<P>,
    #[new(default)]
    z: T,
}

let _ = Generic::<i32, u8>::new("Hello");

If you have suggestion to replace Rayon and Crossbeam on the list or better description to derive_new please send a Pull Request!

1 is fixed!

For 2. I meant someone might though

#[derive(new)]
struct Foo {
    #[new(value = "default")]
    value: String,
}

Foo::new();
Foo::new("bar");

would work, since python supports optional argument.

It's not a big problem at all, just a small suggestion.
So I think it's up to you, who is the owner of this awesome list, to decide whether to change it or not.
