Struct Final 

pub struct Final<T>(/* private fields */);

This no-std crate provides the Final, struct which guarantees the interior immutability of the value that it wraps. This is useful for preserving invariants on the fields of structures, whose ‘safe’ mutation would cause undefined behavior. Wraps a value in the Final type, which does not give out mutable references.
