In my current position I've had to swap to full time Rust development.
|
||
|
|
After about 2 months of full time Rust development I think I'll likely be developing projects in Rust in the future instead of C++ when performance is important.
|
||
|
|
My reasons for this are primarily:
|
||
|
|
|
||
|
|
1. Just Works™ build system and crates.io makes drawing in libraries painless
|
||
|
|
2. Guaranteed memory safety is pretty nice
|
||
|
|
3. Syntax is much cleaner and succinct than C++, with lots of nice syntax sugar to sweeten the package
|
||
|
|
4. Easily integrable with C (and therefore C++ with some massaging)
|
||
|
|
5. Proc macros are pretty nice as well
|
||
|
|
6. Built-in test framework
|
||
|
|
|
||
|
|
I think that point 3 is potentially the biggest factor for me as the C++ modern syntax is not what I would consider clean, especially if you are trying to use a more functional programming style.
|
||
|
|
A simple example highlighting the difference:
|
||
|
|
|
||
|
|
**C++**
|
||
|
|
```c++
|
||
|
|
vector<int> v(10,1);
|
||
|
|
std::transform(v.cbegin(), v.cend(), v.begin(), [](int value){ value + 1;})
|
||
|
|
```
|
||
|
|
|
||
|
|
**Rust**
|
||
|
|
```rust
|
||
|
|
let v = vec![1;10];
|
||
|
|
let v = v.map(|val| val + 1).collect()
|
||
|
|
```
|
||
|
|
**I think that speaks for itself...**(Although I prefer the C++ lambdas which don't auto capture)
|
||
|
|
|
||
|
|
I'm not sure that I consider myself a Rustacean though as some seemingly simple programming tasks can become huge mountains due to the borrow rules Rust enforces.
|
||
|
|
Once you learn the borrow rules and some of the tricks, the language itself ends up being very clean to write and easy to test.
|
||
|
|
I probably won't be writing C++ in the future unless I have a very specific/niche reason to.
|
||
|
|
I recommend checking Rust out if you haven't yet, it may surprise you!
