Why stop there and not go all the way to pub fn read(path: Path) -> Bytes { File::open(path).read_to_end() }

  How to return an error in your example?

    Throw an exception proving the point of the article even further

      You would actually use a Result type: use std::io; pub fn read(path: Path) -> io::Result<Bytes> { File::open(path)?.read_to_end() }

        Sure, if you are allowed to change the signature, makes it look more ugly than just returning Bytes though

    pub fn read(path: Path) -> Result<Bytes> { File::open(path)?.read_to_end() } isn't so bad either.

      Exactly, and this is in my experience what most Rust code ends up looking like. It compromises a bit on generality and (potential) performance to achieve better readability and succinctness. Often a worthwhile trade-off, but not something the standard library can always do.
