Scalar types are types representing a single value. Moreover primitive types contains scalar types and some others. See: https://doc.rust-lang.org/std/index.html#primitives
Types that have the copy traits are said to have copy semantics. What this means is that when you pass them into a function, you pass a copy of that value into that function.
Non-primitive types do not have the Copy trait by default. This means they are subject to move semantics. When you pass them into a function, you move the value into that function. Without going into details (that I am still learning about myself), this pretty much means that when the function scope ends, the value is destroyed.
There are ways to deal with this, using a reference for instance.
It is the symbol & that says take the reference

Les raisons de l'évolution des températures corporelles ne sont pas expliquées précisément par les scientifiques, même si les hypothèses tournent autour de l'amélioration de l'hygiène de vie et de la réduction des maladies inflammatoires.
Only one same job at a time ?
My solution to deal with this is to bind an IPv6 localhost ::1 socket to a given port. Only one process can do this, and thus it’s a very effective mutex. No lock files to cause havoc, no dealing with the dark and buggy corners of advisory file locking.
For shell scripts, simply replace the #!/bin/sh with #!/somewhere/bin/lock 2048 where 2048 is the port number you will use to enforce the lock (greater than 1024 if you do not want to deal with the hassles of privileged ports).

Mais si Google peut éviter de payer des impôts en France... autant le faire. En revanche traquer les mauvais payeur, ça oui !
Google, comme tous les GAFAM et BATX ne sont intéressés que par une seule chose: eux-même et leur propres intérêts. Si ils agissent dans l'intérêt d'autrui, ce n'est que pour leur propre intérêt en retour.
En voici un autre exemple.
