Thanks for replying Steve. I appreciate all of the work you do make rust accessible to new programmers. Don't mind the downvotes as I just wrote from vague memory without properly verifying things. I tried to look through my Google history to see how I landed into that specific problem. But was not able to find out how exactly I landed on that syntax issue about writing files. If it helps here is my chronological Google Search and visit history on that day about how I finally went from "try" macro to understanding how "?" operator is used in Rust. * Searched for "try macro rust" * Visited "std::try! - Rust" * Visited "Learning to 'try!' things in Rust - Jonathan Turner" * Searched for "rust expected expression, found reserved keyword `try`" * Visited "Try keyword reservation breaks macro try - The Rust Programming ..." * Searched for "rust try macro removed" * Visited "Error Handling - The Rust Programming Language" * Visited "How to use ? and catch in Rust? - Stack Overflow" * Searched for "rust optional unwrapping" * Visited "What is unwrap in Rust, and what is it used for? - Stack Overflow" * Visited "Killing unwrap() • Dimitri Merejkowsky - dmerej.info" * Searched for "rust ? operator" * Visited "The ? operator for easier error handling - The Edition Guide"
