Would https://doc.rust-lang.org/std/primitive.str.html#method.eq_ignore_ascii_case be even better in this case? |

it's not a str it's a char, so https://doc.rust-lang.org/std/primitive.char.html#method.eq_ignore_ascii_case but why not. Even better is left in the eye of the beholder, because it's just a shorthand for what's in this PR. but since it's not in a rollup yet, let's do that @xizheyin @bors r- |

Use `to_ascii_lowercase` to avoid heap alloc in `detect_confuse_type` A small optimization has been made, using `to_ascii_lowercase()` instead of `to_lowercase().to_string()`. r? compiler

It's in a rollup now...., race condition, or bors not seeing edits, no worries. Another PR will be fine, not in this one @xizheyin |

Re-approving explicitly, bors state was weird. @bors r=lqd |

The rollup failed. Based on the conversation above, I'm assuming you would prefer to modify this PR instead of merging it as-is. @bors r- |
