I think this is better implemented as a for loop:

let working_directory = context.working_directory();

for attribute in self.attributes {
  if let Attribute::WorkingDirectory(dir) = attribute {
    return Some(working_directory.join(dir.cooked);
  }
}

Some(working_directory)

Also note the use of cooked, which is the contents of the string literal after processing escape sequences.

Yup, the suggested for loop reads better and is more concise. Just curious, is there any other reason you suggested this refactor?

Good to know - thanks for the info!

Duplicate working directory attributes should be an error.
