Adding feature to "accept" a clippy suggestion

[Will-Low]

Clippy has some great suggestions that contain working code, like the message below:

   --> src/data_types.rs:143:63
    |
143 |                   hashed_conditions.get(&condition.description).expect(
    |  _______________________________________________________________^
144 | |                     format!(
145 | |                         "[ERROR] condition in play \"{}\" not found in \"conditions.yaml\".",
146 | |                         &condition.description
147 | |                     )
148 | |                     .as_str(),
149 | |                 );
    | |_________________^ help: try this: 'unwrap_or_else(|| panic!("[ERROR] condition in play \"{}\" not found in \"conditions.yaml\".", &condition.description))'
    |

I'd like to set a flag that makes these lint suggestions interactive. I'd like to be able to accept a code suggestion provided by clippy and have clippy update the code in my file. Would be curious to get other peoples' take on this idea.

This is going to be possible in one of the upcoming rust releases, it should be available on nightly once rust-lang/rust#62914 is merged and included in a nightly. The feature will initially be available via cargo fix --clippy.

There is some more work to be done on the Clippy side to make the suggestions more correct, though.

As @phansch mentioned, this feature was recently implemented in cargo. Here's the PR: rust-lang/cargo#7069

It will be available through cargo fix --clippy -Zunstable-options on nightly soon.
