Struct TypedFunction

pub struct TypedFunction<'lua, Params, Response>
where
    Params: TypedMultiValue,
    Response: TypedMultiValue,
{ /* private fields */ }

Helper to bake the type information for a lua Function. This makes repeated calls to the Function’s call all the same with enforced arguments and return types.

Implementations

impl<'lua, Params, Response> TypedFunction<'lua, Params, Response>

where Params: TypedMultiValue + IntoLuaMulti<'lua>, Response: TypedMultiValue + FromLuaMulti<'lua>,

pub fn call(&self, params: Params) -> Result<Response>

Same as Function::call but with the param and return types already specified

pub unsafe fn call_unsafe(&self, params: Params) -> Response

Same as Function::call but with the param and return types already specified

Safety

Panics if any lua errors occur

pub fn from_rust<F>(&self, lua: &'lua Lua, func: F) -> Result<Self>

where Params: TypedMultiValue + FromLuaMulti<'lua>, Response: TypedMultiValue + IntoLuaMulti<'lua>, F: Fn(&'lua Lua, Params) -> Result<Response> + MaybeSend + 'static,

Create a typed function from a rust function.

This will call Lua::create_function under the hood
