The match operator

A powerful tool for handling control flow in Rust is the match operator. It compares a value against a set of patterns and executes code based on which pattern matches.

match result {
  Ok(content) => handle(content),
  Err(error) => panic!("Can't deal with: {}", error),
}

"The power of match comes from the expressiveness of the patterns and the fact that the compiler confirms that all possible cases are handled."
