The rustdoc book says use

[package.metadata.docs.rs]
cargo-args = ["-Zunstable-options", "-Zrustdoc-scrape-examples=examples"]

...but my build failed with error

cc @willcrichton @jyn514 could you provide some input here?

Thanks!

The rustdoc book documents rustdoc flags. You are passing this flag to cargo. I don't remember how to configure cargo for this argument off the top of my head, but you should look in the cargo book for how.

Oh wait, apparently the rustdoc book directly documents using this with docs.rs?? it's probably just outdated then - I'll transfer this to rust-lang/rust.

Btw it works fine after taking out the "=examples"
