=====

Lua bindings for Rust, oriented around macros.

Modeled loosely after [PyO3](https://pyo3.rs/). Based on [mlua](https://docs.rs/mlua).

**WARNING**: This software is *ALPHA* quality. Expect breaking changes and API removals/additions.

## Examples

```rust

use luao3::prelude::*;

use mlua::prelude::*;

#[derive(Debug, FromLua, ToLua)]

struct Foo {

    foo: String,

    #[lua(default)]

    bar: Vec

}

#[lua_function]

pub fn bar(a: Foo) -> LuaResult {

    Ok(Foo {

        foo: format!("baz{}", a.foo),

        bar: vec!["foo".into(), "baz".into(), a.bar.get(0).cloned()

            .unwrap_or_else(|| "baz".into())]

    })

}

#[lua_function]

pub fn baz(txt: String) -> LuaResult {

    txt.parse::().map_err(mlua::Error::external)

}

luao3::declare_simple_module! {

    name => foobar,

    members => {

        fn bar,

        fn baz as baz2

    }

}
