closure! - A macro for individually capturing variables

This crate provides a macro which lets you write closures that can capture individually either by moving, referencing, mutably referencing of cloning.

Usage

Start by adding an entry to your Cargo.toml:

[dependencies]
closure = "*"

Then import the crate with macro use enabled:

#[macro_use]
extern crate closure;

Then you can write closures like so:

let string = String::from("move");
let x = 10;
let mut y = 20;
let rc = Rc::new(5);

let closure = closure!(move string, ref x, ref mut y clone rc {
    ...
});
