Learning Rust and Lemmy

391 readers

Welcome

A collaborative space for people to work together on learning Rust, learning about the Lemmy code base, discussing whatever confusions or difficulties we're having in these endeavours, and solving problems, including, hopefully, some contributions back to the Lemmy code base.

Rules TL;DR: Be nice, constructive, and focus on learning and working together on understanding Rust and Lemmy.

Running Projects

Policies and Purposes

  1. This is a place to learn and work together.
  2. Questions and curiosity is welcome and encouraged.
  3. This isn't a technical support community. Those with technical knowledge and experienced aren't obliged to help, though such is very welcome. This is closer to a library of study groups than stackoverflow. Though, forming a repository of useful information would be a good side effect.
  4. This isn't an issue tracker for Lemmy (or Rust) or a place for suggestions. Instead, it's where the nature of an issue, what possible solutions might exist and how they could be or were implemented can be discussed, or, where the means by which a particular suggestion could be implemented is discussed.

Rules

  1. Lemmy.ml rule 2 applies strongly: "Be respectful, even when disagreeing. Everyone should feel welcome" (see Dessalines's post). This is a constructive space.
  2. Don't demean, intimidate or do anything that isn't constructive and encouraging to anyone trying to learn or understand. People should feel free to ask questions, be curious, and fill their gaps knowledge and understanding.
  3. Posts and comments should be (more or less) within scope (on which see Policies and Purposes above).
  4. See the Lemmy Code of Conduct
  5. Where applicable, rules should be interpreted in light of the Policies and Purposes.

Hot takes on the state of Rust v C/C++ for safety (mastodon cross post) (pony.social)

The post mentions data or research on how rust usage in is resulting in fewer errors in comparison to C. Anyone aware of good sources for that?

Anecdotally I converted a python app to rust and suddenly had no more runtime errors. It’s utter bliss.

That’s interesting. What made the difference? The type system? Or memory safety constraints forcing more correct logic?

[–] [email protected] 4 points 3 months ago (1 children)

Both. It allowed/forced me to explicitly handle edge cases I wasn’t thinking about. That means the error doesn’t happen at run time, but at compile time (or while writing!) so technically speaking the errors didn’t go away, they moved to in my face rather than “maybe in the future.”

Most of the time the remedy was to explicitly catch whatever happened and nicely explain what happened, vs looking at empty production logs because logging is turned down.

It’s certainly a preference, but for me, I’d rather argue with the compiler all day long and push a bulletproof release than quickly ship something I thought was good and be embarrassed.

while writing!

Yea, understated IMO how much the compiler requirements actually manifest directly in the writing process with LSPs etc.

Yea even that is making the logic more water tight.
