What are the best practices for using traits in Rust?

When using traits in Rust, it's important to keep them focused and cohesive. Each trait should represent a single responsibility.

Can you give an example of a well-defined trait?

Sure! A good example is the Iterator trait, which defines a single method, next(), that returns the next item in a sequence.

How do I implement a trait for my struct?

You can implement a trait for your struct by using the impl keyword followed by the trait name and the struct name. For example: impl MyTrait for MyStruct { ... }.

What about trait bounds? How should I use them?

Trait bounds are used to specify that a generic type must implement a certain trait. This helps ensure type safety and allows you to use trait methods.
