Turns out that `doc_markdown` uses a non-cheap rustdoc function to convert from markdown ranges into source spans. And it was using it a lot (about once every 17 lines of documentation on `tokio`, which ends up being about 2000 times). This ended up being about 18% of the total Clippy runtime as discovered by lintcheck --perf in docs-heavy crates. This PR optimizes one of the cases in which Clippy calls the function, and a future PR once pulldown-cmark/pulldown-cmark#1034 is merged will be opened. This PR lands the use of the function into the single-digit zone. Note that not all crates were affected by this crate equally, those with more docs are affected far more than those light ones. changelog:[`clippy::doc_markdown`] has been optimized by 50% |
