}

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

Required Methods

fn call<A, R>(&self, args: A) -> Result<R, Error>

where A: IntoLuaMulti<'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_method<A, R>(&self, name: &str, args: A) -> Result<R, Error>

where A: IntoLuaMulti<'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<A, R>(&self, name: &str, args: A) -> Result<R, Error>

where A: IntoLuaMulti<'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.
