I'm a big fan of Rust.
cargo
) just works, the compiler's error messaging is simply unmatched and the IDE story is excellent thanks torust-analyzer
.Result
and you have to explicitly handle the possibility that something went wrong. There's no forgetting a null check and slamming face-first into aNullReferenceException
or segfault in some other part of your code.Obviously it's not all perfect, however.
rustc
is always getting faster, of course, but it'll probably never be as fast as Go or JVM/NET.)And much time is saved from debugging. It makes a lot of sense that we let the computer/compiler keep an eye on lifetimes, allocations and access so the code is much more correct once it compiles.
I feel like my old colleagues and I have spent a far too large part of the last 20 years chasing memory issues in C++. We are all fallible, let the compiler do more.
I like the way the compiler doesn't just tell you there's a problem, but also gives you advice on ways you may be able to fix it. That's a smart compiler.
And I like the way I can write something that runs fast but not feel faintly anxious all the time I'm doing it.
