It's "perfectly valid, fine" with the exception that it's different from how the vast majority of Rust programmers write code. That in itself is a problem. Rust has two widely-used tools that enforce style: `rustfmt` and `clippy`. The former enforces formatting style and the latter general programming style, such as whether or not to use a `return` statement (`clippy` also does non-style lints). For many of these formatting/stylistic lints, there are valid arguments to be made for an alternative choice. I personally often disagree with one or both tools. I still follow them. The huge benefit here is that most Rust codebases look identical. I can open up burntsushi's regex crate and see code that is formatted and styled exactly like mine. It makes reading new code a lot easier.
