Exclusive

A procedural macro for wrapping code in a collision-free context.

Installation

This crate is available on crates.io and can be used by adding the following to your project's Cargo.toml:

[dependencies]
exclusive = "0.1.0"

and this to your crate root (main.rs or lib.rs):

#[macro_use]
extern crate exclusive;

Usage

The exclusive! macro allows for placing blocks of code in a context that won't collide with other calls to the macro in the same namespace:

exclusive! {
    let x = 20;
    let y = 30;
}

exclusive! {
    // This code doesn't actually run
    println!("Hello, world!");
}

Purpose

This project was made to be used by static_assertions to prevent different assertions from colliding with the same identifier.
