wrong, rust is about exclusive ptr access, nothing more. you cannot do ReadOnly<T> in rust.

Why not? Isn't that &T like a read only wrapper of T?

try to do ReadOnly<T> yourself, and then put Cell into it, or RwLock, or Mutex, or Atomic, or crossbeam channel, ...

it LOOKS like it's possible but it can be broken easily. again, because rust is not really about (i)mutability, it's about mem-safety - and all of those can be safely mutated with &T
