However, the requirements for this software are as stringent as ever: it must not only be fast, it must be “safe”, i.e. able to process untrusted data without crashing or being vulnerable to security exploits. . Traditionally, these two requirements have been at odds: network programmers had to pick a language that either offered speed or safety.Enter Rust, a...
