new lint: `eager_transmute` A small but still hopefully useful lint that looks for patterns such as `(x < 5).then_some(transmute(x))`. This is almost certainly wrong because it evaluates the transmute eagerly and can lead to surprises such as the check being completely removed and always evaluating to `Some` no matter what `x` is (it is UB after all when the integer is not a valid bitpattern for the transmuted-to type). [Example](https://godbolt.org/z/xoY34fPzh). The user most likely meant to use `then` instead. I can't remember where I saw this but this is inspired by a real bug that happened in practice. This could probably be a correctness lint? changelog: new lint: [`eager_int_transmute`] |
