+[Prusti](http://www.pm.inf.ethz.ch/research/prusti.html) is a prototype verifier for Rust that makes it possible to formally prove absence of bugs and correctness of code contracts. Internally, Prusti builds upon the [Viper verification infrastructure](http://www.pm.inf.ethz.ch/research/viper.html).
 
 By default Prusti verifies absence of integer overflows and panics, proving that statements such as `unreachable!()` and `panic!()` are unreachable.
 Overflow checking can be disabled with a configuration flag, treating all integers as unbounded.
 In Prusti, the functional behaviour of functions and external libraries can be specified by using annotations, among which are preconditions, postconditions, and loop invariants.
 The tool checks them, reporting error messages when the code does not adhere to the provided specification.
