Nontrivial Lua binding from Rust, with C equivalent.

1.c

#include <stdio.h>
#include <stdlib.h>
#include <lua.h>
#include <lauxlib.h>
#include <lualib.h>

int main()
{
    lua_State *L = luaL_newstate();

    if (luaL_dostring(L, "function foo (x,y) return x+y end")) exit(1);

    lua_getglobal(L, "foo");

    lua_pushinteger(L, 5);
    lua_pushinteger(L, 3);

    lua_call(L, 2, 1);
    printf("Result: %d\n", lua_tointeger(L, -1));

    lua_close(L);

    return 0;
}

1.rs

mod lua52;

fn main() {
    let lua = lua52::LuaState::new();

    if lua.L_dostring("function foo (x,y) return x+y end") {
        fail!();
    }

    lua.getglobal("foo");

    lua.push(5);
    lua.push(3);

    lua.call(2, 1);
    println(fmt!("Result: %?", lua.tointeger(-1)));
}
