Clippy marks question code as incorrect Understanding Ownership / What is ownership / Who Owns the One Ring #272

Closed edutools-service closed 1 year ago

edutools-service commented 1 year ago

With Clippy enabled, the IDE shows an error (red underline) for this section of code:

    let sam = frodo;
    let frodo = sam;

It complains that it looks like the code is trying to swap the two variables, and that I should use std::mem::replace instead. The check in the Description window continues to succeed as expected in spite of the error in the editor.
