The Clone trait for types that cannot be "implicitly copied"
In Rust, some simple types are "implicitly copyable" and when you assign them or pass them as arguments, the receiver will get a copy, leaving the original value in place. These types do not require allocation to copy and do not have finalizers (i.e. they do not contain owned pointers or implement Drop), so the compiler considers them cheap and safe to copy and automatically implements the Copy trait for them. For other types copies must be made explicitly, by convention implementing the Clone trait and calling the clone method.
