Struct rlua::LuaUserData

pub struct LuaUserData<'lua>(_);

Handle to an internal instance of custom userdata. All userdata in this API is based around RefCell, to best match the mutable semantics of the Lua language.

Methods

impl<'lua> LuaUserData<'lua>

fn is<T: LuaUserDataType>(&self) -> bool

Checks whether T is the type of this userdata.

fn borrow<T: LuaUserDataType>(&self) -> LuaResult<Ref<T>>

Borrow this userdata out of the internal RefCell that is held in lua.

fn borrow_mut<T: LuaUserDataType>(&self) -> LuaResult<RefMut<T>>

Borrow mutably this userdata out of the internal RefCell that is held in lua.
