Mara Bos caca256b52 Rollup merge of #88503 - m-ou-se:array-into-inter-ambiguous, r=cjgillot ... Warn when [T; N].into_iter() is ambiguous in the new edition. Fixes https://github.com/rust-lang/rust/issues/88475 In https://github.com/rust-lang/rust/issues/88475, a situation was found where `[T; N].into_iter()` becomes *ambiguous* in the new edition. This is different than the case where `(&[T; N]).into_iter()` resolves differently, which was the only case handled by the `array_into_iter` lint. This is almost identical to the new-traits-in-the-prelude problem. Effectively, due to the array-into-iter hack disappearing in Rust 2021, we effectively added `IntoIterator` to the 'prelude' in Rust 2021 specifically for arrays. This modifies the prelude collisions lint to detect that case and emit a `array_into_iter` lint in that case.		2021-08-31 10:41:29 +02:00
