I personally prefer the memory safety tools offered by D over Rust. D also doesn’t come with const by default, and you can even opt out of the RAII stuff a certain graphics driver developer boasted about in the Linux developer mailings (RAII can be a bad for optimization).
Not if you opt in it. You can even put
@safe:
in the beginning of your D source code, then you’ll have a memory safe D (you have to opt out by using@trusted
then@system
).
