new-macro

This is a macro to automate creating a 'new' function for structs

Examples

Here is a basic sample of the macro in action!

Source Code:

use new_macro::New;
#[derive(New)]
struct Test {
    a: i32,
    #[default(a * 2)]
    b: i32,
}

Generated Code:

struct Test {
    a: i32,
    b: i32,
}

impl Test {
    pub fn new(a: i32) -> Self {
      Self {
        a,
        b: a * 2,
      }
    }
}
