Crate smile_marco 

smile-marco provides macros such as Getter, Setter, Wither, Builder, etc

These macros generate methods such as get, set, with, and builder for properties within a struct, providing quick access and manipulation. Convenient for daily development.

[dependencies]
smile-marco = { version = "1.0.0", features = ["full"] }
#or
smile-marco = { version = "1.0.0"}

If needed, use partial macros.

[dependencies]
smile-marco = { version = "1.0.0", features = ["getter","setter"] }

Example

use smile_marco::{Builder, Getter, Setter, Wither};

#[derive(Builder, Getter, Setter, Wither)]
struct Book {
    title: String,
    #[name(cost)] // rename
    price: i32,
    #[exclude] // Do not generate set methods for author
    author: String,
}


let mut book = Book::builder()
.title("Rust Programming".to_string())
.price(100)
.author("rust".to_string())
.build();
assert_eq!(book.title, "Rust Programming".to_string());
book.set_title("Rust Book".into());
assert_eq!(book.title, "Rust Book".to_string());
assert_eq!(book.get_cost(), &100);
let mut book = book.with_cost(|c| c + 100);
assert_eq!(book.price, 200);
