# Code Style
hyper uses the default configuration of `rustfmt`.
## cargo fmt
`cargo fmt --all` does not work in hyper. Please use the following commands:
```txt
# Mac or Linux
rustfmt --check --edition 2021 $(git ls-files '*.rs')
# Powershell
Get-ChildItem . -Filter "*.rs" -Recurse | foreach { rustfmt --check --edition 2021 $_.FullName }
```
> **NOTE**: If you are using `rust-analyzer`, you can add the following two lines in your `settings.json` to make sure the features get taken into account when checking the project:
>
> ```json
> "rust-analyzer.cargo.features": ["full"],
> "rust-analyzer.check.features": ["full"],
> ```
