Derive Macro Data 

#[derive(Data)]
{
    // Attributes available to this derive:
    #[set]
    #[get]
    #[get_mut]
}

This is an example of how to use the Lombok procedural macro with get, get_mut, and set attributes.

The Lombok procedural macro is used to automatically generate getters, mutable getters, and setters for struct fields. The get and get_mut attributes control the visibility of the getter functions, while the set attribute controls the visibility of the setter function.

Example:

use lombok_macros::*;

#[derive(Data, Debug, Clone)]
struct LombokTest<'a, 'b, T: Clone> {
    #[get(pub(crate))]
    #[set(pub(crate))]
    list: Vec<String>,
    #[get(pub(crate))]
    opt_str_lifetime_a: Option<&'a T>,
    #[set(private)]
    opt_str_lifetime_b: Option<&'b str>,
}
let mut data: LombokTest<usize> = LombokTest {
    list: Vec::new(),
    opt_str_lifetime_a: None,
    opt_str_lifetime_b: None,
};
let list: Vec<String> = vec!["hello".to_string(), "world".to_string()];
data.set_list(list.clone());
match data.get_list() {
    left_val => {
        assert_eq!(*left_val, list);
    }
}
