aksr

A Rust derive macro designed to simplify struct management by automatically generating getter and setter methods for both named and tuple structs. The macro supports customizations such as method prefixes, aliases, and incrementable fields, enhancing code readability and reducing boilerplate.

Installation

Add aksr to your Cargo.toml dependencies:

[dependencies]
aksr = "0.0.1"

Example

This example demonstrates the use of aksr with a named struct.

use aksr::Builder;

#[derive(Builder, Debug, Default)]
struct Rect {
    x: f32,
    y: f32,
    w: f32,
    h: f32,
    #[args(
        alias = "attributes",
        setter_prefix = "set",
        inc = true,
        getter = false
    )]
    attrs: Vec<String>,
}

fn main() {
    let rect = Rect::default()
        .with_x(0.0)
        .with_y(0.0)
        .with_w(10.0)
        .with_h(5.0)
        .set_attributes(&["A", "X", "Z"])
        .set_attributes_inc(&["O"])
        .set_attributes_inc(&["P"]);

    println!("rect: {:?}", rect);
    println!("x: {}", rect.x());
    println!("y: {}", rect.y());
    println!("w: {}", rect.w());
    println!("h: {}", rect.h());
    println!("attrs: {:?}", rect.attrs);
    // println!("attrs: {:?}", rect.attrs()); // Method `attrs` is not generated
}

Code Expanded

struct Rect {
    x: f32,
    y: f32,
    w: f32,
    h: f32,
    #[args(alias = "attributes", setter_prefix = "set", inc = true, getter = false)]
    attrs: Vec<String>,
}
impl Rect {
    pub fn with_x(mut self, x: f32) -> Self {
        self.x = x;
        self
    }
    pub fn x(&self) -> f32 {
        self.x
    }
    pub fn with_y(mut self, x: f32) -> Self {
        self.y = x;
        self
    }
    pub fn y(&self) -> f32 {
        self.y
    }
    pub fn with_w(mut self, x: f32) -> Self {
        self.w = x;
        self
    }
    pub fn w(&self) -> f32 {
        self.w
    }
    pub fn with_h(mut self, x: f32) -> Self {
        self.h = x;
        self
    }
    pub fn h(&self) -> f32 {
        self.h
    }
    pub fn set_attributes(mut self, x: &[&str]) -> Self {
        self.attrs = x.iter().map(|s| s.to_string()).collect();
        self
    }
    pub fn set_attributes_inc(mut self, x: &[&str]) -> Self {
        if self.attrs.is_empty() {
            self.attrs = x.iter().map(|s| s.to_string()).collect();
        } else {
            let mut x = x.iter().map(|s| s.to_string()).collect::<Vec<_>>();
            self.attrs.append(&mut x);
        }
        self
    }
}
