Posting Etiquette
-
Ask the main part of your question in the title. This should be concise but informative.
-
Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.
-
Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.
-
Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

Also, with Rust, if you're optimizing for performance and not legibility, it's actually pretty important to not prematurely optimize. Its type system gives the compiler a lot of information to work with, and it does a really good job finding places where code can be optimized.
What might make sense in some languages, such as trying to cache small strings instead of recomputing them, can actually hurt performance by preventing the compiler from using certain optimizations.
