I don't think this is necessary. See my comment on #6314. |

I'm going to close this because it's been sitting here for a month, has gone stale, and doesn't seem to be going to get an r+. Feel free to reopen once #6314 is resolved. |

…, r=Manishearth Avoid slice indexing in Clippy (down with the ICEs) While working on rust-lang#7569 I got about 23 lint reports where we can avoid slice indexing by destructing the slice early. This is a preparation PR to avoid fixing them in the lint PR. (The implementation already takes about 300 lines without tests 😅). Either way, this should hopefully be easy to review 🙃 --- changelog: none

…steffen New lint `index_refutable_slice` to avoid slice indexing A new lint to check for slices that could be deconstructed to avoid indexing. This lint should hopefully prevent some panics in other projects and ICEs for us. See rust-lang#7569 for an example The implementation specifically checks for immutable bindings in `if let` statements to slices and arrays. Then it checks if these bindings are only used for value access using indices and that these indices are lower than the configured limit. I did my best to keep the implementation small, however the check was sadly quite complex. Now it's around 300 lines for the implementation and the rest are test. --- Optional future improvements: * Check for these instances also in `match` statements * Check for mutable slice bindings that could also be destructed --- changelog: New lint [`index_refutable_slice`] I've already fixed a bunch of lint triggers in rust-lang#7638 to make this PR smaller Closes: rust-lang#7569
