clonelicious

Official Documentation

A Rust macro library that simplifies cloning and closure execution. The clone! macro automatically clones variables and immediately executes the closure with the cloned values, streamlining common patterns in Rust programming.

Installation

To install clonelicious run cmd:

cargo add clonelicious

Usage

use clonelicious::*;

let s1: String = String::from("Hello");
let s2: String = String::from("World");
let res: String = clone!(s1, s2 => {
    assert_eq!(s1, String::from("Hello"));

    format!("{} {}", s1, s2)
