I'm confused, have you found the try operator ("?") insufficient for your use cases? I believe it does what you are describing, ex: fn process_file(p: Path) -> Result<String, io::Error> { let file = File::open(p)?; //Return err if file can't be opened let mut out = String::new(); file.read_to_string(&mut out)?; // Return err if read fails out } If you want to handle the error case within the same function `try` blocks are available in nightly[0] and will eventually come to stable[1] [0] https://doc.rust-lang.org/nightly/unstable-book/language-features/try-blocks.html https://doc.rust-lang.org/nightly/unstable-book/language-fea...
