It’s actually not legal in the Netherlands, it’s a very strange and frankly kind of bad set up. This is what the other commenter meant with “fake legalization”.

The issues here are largely with the EU which stops it from being sold in stores. For now, possession is legalised and you can have all previous arrests made because you were carrying up to 25g permanently removed from your record. It also legal to grow at home.
In this sense, it is legal for personal use but not for commercial use. To get access to weed, they will be rolling out “cannabis social clubs” in summer in which you need to be a member to be allowed to buy weed. These clubs are not allowed to make a profit. There is a plan to later do some tests with commercial usage but its not clear where that is on the roadmap.
It will be interesting to see if this will have any effects on the EU. I can imagine if more countries want to support the legalization that some hurdles can be removed there.
I think Rust actually is actually among the best in this regard for the simple reason that there is consistency given by the compiler. A simple cargo fmt and cargo build will fix or warn you about everything. I can read into Rust codebases so quickly. C++ was always really exhausting because most of the time you were just getting used to the code style.
Considering the position Germany has in the EU, this is very unlikely
