Agree with what was pointed out from feedback. Scraped examples from lib internal might bring more confusing, non-user-facing code usages. The intent of computing scrape units is also clearer than it was by having a separate method.
Thank you for continuing tuning on this! Only some nits left.
Thanks for suggestions, just incorporated both. |
Thanks! @bors r+ |

What does this PR try to resolve?
Based on some early feedback about the scrape-examples feature, both documentation authors and consumers did not consider examples useful if they are scraped from a library's internals, at least in the common case. Therefore this PR changes the default behavior of
-Zrustdoc-scrape-examples
to only scrape from example targets, although library targets can still be configured for scraping.How should we test and review this PR?
I have updated the
docscrape
tests to reflect this new policy, as well as the Unstable Options page in the Cargo book.r? @weihanglo
