Should I choose Ada, SPARK, or Rust over C/C++?

At AdaCore, we’re in the business of supporting people who develop high-integrity software, in particular for embedded systems. In terms of programming languages, this means supporting the most commonly found candidates, which in 2024 include C/C++, Ada/SPARK, and Rust. If you’ve already made your decision, we will support you. However, in a number of situations, people ask us: “What should we do? What’s the best out there?”. While it’s difficult to give a one-size-fits-all answer, there are some strategic elements to consider.

Memory Safety in Rust

Informally, memory safety in a program means that each data access is well behaved; i.e., is consistent with the item’s data type, does not impinge on any storage locations beyond the data value’s boundaries, and, if the program is multithreaded, does not produce an inconsistent or corrupted value. Memory safety violations result in undefined behavior, which is a Bad Thing: instances like the notorious “buffer overrun” can turn an otherwise safe and secure program into a ticking virtual time bomb. Some of the most eventful malware attacks in recent years are due to memory safety violations, and the topic has moved from techno-geek subreddits into mainstream discourse. Anyone developing or acquiring software, especially for applications with high assurance requirements, needs to pay attention.
