Struct Caller

#[non_exhaustive]
pub struct Caller<'a, UserData = ()> {
    pub user_data: &'a mut UserData,
    pub instance: &'a mut RawInstance,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

user_data: &'a mut UserData

instance: &'a mut RawInstance
