Struct gluon_vm::api::Opaque

pub struct Opaque<T, V>(/* private fields */)
where
    V: ?Sized;

Type implementing both Pushable and Getable of values of V regardless of wheter V implements the traits. The actual value, V is only accessible directly either by Deref if it is Userdata or a string or by the to_value method if it implements Getable.

When the value is not accessible the value can only be transferred back into gluon again without inspecting the value itself two different threads.
