Extension trait for rlua::Scope

Required Methods§

Source

fn create_async_function<Arg, Ret, RetFut, F>( &self, ctx: Context<'lua>, func: F, ) -> Result<Function<'lua>>
where Arg: 'scope + for<'all> FromLuaMulti<'all>, Ret: 'scope + for<'all> ToLuaMulti<'all>, RetFut: 'scope + Future<Output = Result<Ret>>, F: 'scope + for<'all> Fn(Context<'all>, Arg) -> RetFut,

Wraps a Rust function or closure, creating a callable Lua function handle to it. See also rlua::Scope::create_function and ContextExt::create_async_function.

The where clause stipulates a few additional constraints compared to rlua::Scope::create_function. This is required for compiling the implementation, and should not be an issue. If it is, please report a bug to rlua-async with instructions on how to reproduce and your use case.

Source

fn create_async_function_mut<Arg, Ret, RetFut, F>( &self, ctx: Context<'lua>, func: F, ) -> Result<Function<'lua>>
where Arg: 'scope + for<'all> FromLuaMulti<'all>, Ret: 'scope + for<'all> ToLuaMulti<'all>, RetFut: 'scope + Future<Output = Result<Ret>>, F: 'scope + for<'all> FnMut(Context<'all>, Arg) -> RetFut,

Wraps a mutable Rust function or closure, creating a callable Lua function handle to it. See [rlua_async::ScopeExt::create_async_function] for more details.
