An extension trait for Tables that provides a variety of convenient functionality.

Required Methods

fn call<A, R>(&self, args: A) -> Result<R>where
    A: ToLuaMulti<'lua>,
    R: FromLuaMulti<'lua>,

Calls the table as function assuming it has __call metamethod.

The metamethod is called with the table as its first argument, followed by the passed arguments.

fn call_async<'fut, A, R>(&self, args: A) -> LocalBoxFuture<'fut, Result<R>>where
    'lua: 'fut,
    A: ToLuaMulti<'lua>,
    R: FromLuaMulti<'lua> + 'fut,

Asynchronously calls the table as function assuming it has __call metamethod.

The metamethod is called with the table as its first argument, followed by the passed arguments.

fn call_method<K, A, R>(&self, key: K, args: A) -> Result<R>where
    K: ToLua<'lua>,
    A: ToLuaMulti<'lua>,
    R: FromLuaMulti<'lua>,

Gets the function associated to key from the table and executes it, passing the table itself along with args as function arguments.

This is a shortcut for table.get::<_, Function>(key)?.call((table.clone(), arg1, ..., argN))

This might invoke the __index metamethod.

fn call_function<K, A, R>(&self, key: K, args: A) -> Result<R>where
    K: ToLua<'lua>,
    A: ToLuaMulti<'lua>,
    R: FromLuaMulti<'lua>,

Gets the function associated to key from the table and executes it, passing args as function arguments.

This is a shortcut for table.get::<_, Function>(key)?.call(args)

This might invoke the __index metamethod.

fn call_async_method<'fut, K, A, R>(
    &self,
    key: K,
    args: A
) -> LocalBoxFuture<'fut, Result<R>>where
    'lua: 'fut,
    K: ToLua<'lua>,
    A: ToLuaMulti<'lua>,
    R: FromLuaMulti<'lua> + 'fut,

Gets the function associated to key from the table and asynchronously executes it, passing the table itself along with args as function arguments and returning Future.

Requires feature = "async"

This might invoke the __index metamethod.

fn call_async_function<'fut, K, A, R>(
    &self,
    key: K,
    args: A
) -> LocalBoxFuture<'fut, Result<R>>where
    'lua: 'fut,
    K: ToLua<'lua>,
    A: ToLuaMulti<'lua>,
    R: FromLuaMulti<'lua> + 'fut,

Gets the function associated to key from the table and asynchronously executes it, passing args as function arguments and returning Future.

Requires feature = "async"

This might invoke the __index metamethod.
