Common Traits to Implement

#![allow(unused)]
fn main() {
#[derive(Debug, PartialEq, Eq, PartialOrd, Ord, Hash, Clone /* ... */)]
pub struct MyData {
    pub name: String,
    pub number: usize,
    pub data: [u8; 64],
}
}
- Traits are one of the most potent tools in the Rust language. The language and ecosystem expects you to use them, and so a big part of _predictability_ is what traits are implemented for a type!

  • Traits should be liberally implemented on types you author, but there are caveats!

  • Remember, many traits have the ability to be derived: to have a compiler plugin (macro) write the implementation for you!

  • Authors of ecosystem traits (like De/Serialize) have made derive implementations for traits available to users, leading to very little commitment needed on the developer side for implementing these kinds of traits!
