I had some students come ask me about implementing material from my numerical analysis course (which used Julia) in part of their Rust student group. I’m not an expert, but my feeling is that Rust is a “safer” language, which to me means it must be slower. That is, Rust is designed for “systems” whe…

I think I should recap what was discussed (as I understand it): The cost of bounds checking can be avoided in Rust by compile-time “proofs” of correctness, which are somehow done in the type system. There is also get_unchecked, which is unsafe. So I think the conclusion is that it is possible to a…

Completely agree that numeric conversion papercuts for people trying STEM stuff in Rust are capable of hemorrhaging the joy of computing out of anyone. One of my many gripes in Rust land (and boy do I have a few, in particular to the technical computing aspects) is that you have to rethink from loo…

and if you’re wondering why this says .map(|e| e*e) and not .map(|e| e^2) it’s because ^ in Rust is bitwise xor which is… painful. Math does not usually look like math in Rust and that’s one of the many pain points of why I don’t think Rust is (yet) a good fit for technical computing. We may still…

I’ve spent the last 6 months casually learning about Rust. I think the popularity behind Rust is really driven by how it’s revolutionized putting safe memory management in the hands of users. As some here have pointed out, to some degree this is simply making it more difficult to do anything without…

Rust is wonderful, but sometimes it takes too much workaround to get things down. For example, I can not serialize Box<dyn MyTrait>, with MyTrait implemented some types with generic parameters impl<T> MyTrait for MyStruct<T>. To get to that, I have to use enum or Box everywhere, then in each imple…

I’m afraid the notation was lifted almost directly from Ruby (which some early Rustaceans were close to in the early days: a = [1,2,4] b = a.map{|x| x * x}.sum

Ahh, you’re right here. So with Julia, string indexing must be the same internally as Rust’s .chars().nth(idx).unwrap(). The Rust code is more verbose, less convenient/obvious, but more explicit. In a way this tiny example reflects the broader differences in experiences these languages bring to the …

Rust and Julia are both building on LLVM and if you lurk some forums you can see Rust is pushing up against some issues in LLVMs memory model which I anticipate being incorporated in future llvm releases. So I don’t think it’s an all or none thing here but you’re looking at some aspects of Rust that…

I have written a blog post about Rust vs Julia in scientific computing and would like to have a separate thread for its discussion
