# Notes

## BTreeMap

Consider replacing HashMap with BTreeMap to stop nodes from shifting position constantly on every page load.

## Overall guidelines

- Take refs, return owned
- Avoid opacity
    - Third-party macros
    - Procedural macro attributes
    - Returning opaque types, like `impl Trait`
