enum_ns

==========

A Rust compiler plugin that gives enum variants within a module the old namespacing behavior.

Supplies the `#[promote_variants]` attribute that, when applied to a crate or module, will add `use Enum::{Variant1, Variant2, ..};` to the module for each `enum` definition it contains. For forward-compatibility, does not use globs.

Apply the `#[promote_variants(export)]` for the equivalent `pub use` of the above.

Usage

--------

Add to Cargo.toml:

```

[dependencies.enum_ns]

git = "https://github.com/cybergeek94/enum_ns"

```

Crate example:

```rust

#![feature(phase)]

#![promote_variants]

#[phase(plugin)] extern crate enum_ns;

enum MyEnum {

    Variant1,

    Variant2,

    Variant3,

}

fn main() {

  println!("{}, {}, {}", Variant1, Variant2, Variant3);

}
