 Types in Rust are categorized into kinds, based on various properties of the components of the type.
 The kinds are:
 
-`Freeze`
-  : Types of this kind are deeply immutable;
-    they contain no mutable memory locations
-    directly or indirectly via pointers.
 `Send`
   : Types of this kind can be safely sent between tasks.
     This kind includes scalars, owning pointers, owned closures, and
