Building a small personal project in #Rust to teach myself the language. As I was looking over my code, I noticed a mistake I'd made that technically worked, but was kind of silly so I fixed it.

This got me to wondering if Rust had a linter (it does) because surely I'd made other similar rookie mistakes. I found the linter and ran it on my project. It came back with one result that I already knew about: a value in a struct that doesn't get read because I haven't written that code yet. That was it.

I was surprised. It's still a very small project, but perhaps I'm a more competent developer than I give myself credit for.

Does time::OffsetDateTime::now_local() always fail in a testing context or something? It keeps returning Err(IndeterminateOffset).
#rust

Edit: it's working fine when I use it in src/main.rs.

More musings on #Rust:

I wonder if it would be possible to write an #SNES #ROM in Rust. It seems like exactly the kind of resource-constrained system that would be a prime candidate for that sort of thing. Unfortunately, it seems that the SNES used a custom processor, so it's very possible that I won't be able to specify it as a compile target. A quick search reveals that many people have made SNES emulators in Rust, but at a glace, I see nothing about writing ROMS.

I believe the original NES used an off-the-shelf processor (6502 if memory serves?). Perhaps that's more likely to be supported, but that may be a little too resource constrained.

I shall have to dig deeper into this idea. I love the idea of building a custom ROM rather than just pirating something off the internet.

Has anyone done anything like this? Links to any relevant resources would be very much appreciated.

Newbie #Rust question time:

I wan to use the current_local_offset function from the time library, but I apparently need to import it into my project with the local-offset feature.

I assume I need to specify this in Cargo.toml but for the life of me, I can't figure out how. Can someone point me in the right direction?

People who don't like #Rust: why specifically don't you like it?

I'm in the process of learning it now. There are definitely some things about the language that I can see some as finding irritating (i.e.: the borrowing system). Personally though, I'd rather have a dozen complie-time errors than a single runtime error. This is the reason I tend to gravitate towards Haskell, for instance.

It's certainly not the right language for everything, but if you want better safety in code that needs to be highly efficient, it seems a reasonable alternative to C/C++.
