Share much of its implementation with `manual_map` and should greatly benefit from its previous feedback.
There's no requirement to go to nursery first. I'll try to run this on the most popular crates to see if there's lots of FPs. If not, then I think complexity is fine. |

I ran this on 900 most popular crates. Here's the result. At first glance, it seems to work as expected. I'll try taking a look further when time hopefully allows |

Move common functions to `manual_utils.rs`, better arm matching, use clippy utils `contains_unsafe_block`
There was a problem hiding this comment.
LGTM, and running on this on 900 most popular crates seems fine.
There's quite a bit of build error, but I think it shouldn't be related to the lint itself.

Sounds good! Build failures are on crate where the lint does not trigger indeed |
|
Thanks for this! @bors r+ |

☀️ Test successful - checks-action_dev_test, checks-action_remark_test, checks-action_test |

Share much of its implementation with
manual_mapand should greatly benefit from its previous feedback.I'm sure it's possible to even more refactor both and would gladly take input on that as well as any clippy idiomatic usage, since this is my first lint addition.
I've added the lint to the complexity section for now, I don't know if every new lint needs to go in nursery first.
The matching could be expanded to more than
Some(<value>)to lint on arbitrary struct matching inside theSomebut I've left it like it was formanual_mapfor now.needless_match::pat_same_as_exprprovides a more generic match example.close #8822
