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: 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, ) -> Pin<Box<dyn Future<Output = Result<R, Error>> + 'fut>>

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, Error>

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, Error>

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, ) -> Pin<Box<dyn Future<Output = Result<R, Error>> + 'fut>>

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, ) -> Pin<Box<dyn Future<Output = Result<R, Error>> + 'fut>>

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
