Struct TypedUserdata 

pub struct TypedUserdata { /* private fields */ }

Implementations

impl TypedUserdata

pub fn is<T: 'static>(&self) -> bool

pub const fn is_destructed(&self) -> bool

pub unsafe fn cell_ptr<T: 'static>(&self) -> Option<*mut RefCell<Option<T>>>

Returns the typed userdata cell address for T.

Safety

The userdata object that produced this descriptor must remain alive for any access through the returned pointer. TypedUserdata is not a root.
