Learning Rust and Lemmy

1 users here now

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.

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.

fn main() {
    let a=4;
    let fruit = String::from("Apples");
    how_many(a, fruit);

    println!("the amount was {}", a);         // this works
    println!("the fruit was {}", fruit);      // this fails
