Macro lua 

macro_rules! lua {
    () => { ... };
    (nil) => { ... };
    ($item:expr) => { ... };
    (cstr $item:literal) => { ... };
    ($($key:ident = $val:expr),* $(,)?) => { ... };
    ($([$key:expr] = $val:expr),* $(,)?) => { ... };
}

Provides a simple syntax for constructing lua objects.

This was inspired by the very similar json! macro from serde_json.

Examples

use faf_replay_parser::{lua, lua::LuaObject};

// Basic types
let obj1: LuaObject = lua!(10.0);
let obj2: LuaObject = lua!(nil);
let obj3: LuaObject = lua!(true);
// By default, strings are converted to `LuaObject::Unicode`
let obj4: LuaObject = lua!("foo");
// `LuaObject::String`s need to be explicitly prefixed
let obj5: LuaObject = lua!(cstr "foo");

// Tables use lua syntax
let table1: LuaObject = lua! {
    foo = "bar",
    // Expression evaluation is supported
    bar = 2.0 + 3.0,
};
let table2: LuaObject = lua! {
    ["foo"] = "bar",
    [10.] = true,
    // Trailing comma optional
    [false] = 100.
};
