Rust 101 – 7: Error handling with panic and Result
Share on Mastodon
We learnt about enums and generics last time, which means we’re ready to talk about Result, which is a really nice way of handling errors in Rust, that allows you to be very explicit about what went wrong, but also with a very compact syntax using the ? operator. Before that we discuss `panic!`, which essentially stops your program with an error message, and is useful for handling errors that should never happen.
