I tried this code:

/// [`usize`] /// /// [`usize`][core::usize] pub struct Foo;

Built with cargo +nightly doc --target x86_64-unknown-linux-gnu -Zbuild-std

I expected to see this happen: Rustdoc links properly to traits and intra-doc links, as shown when built with cargo +nightly doc --target x86_64-unknown-linux-gnu

Instead, this happened: When built with -Zbuild-std, rustdoc does not link to these traits or properly resolve intra-doc links, and does not attempt to rectify this by building docs for core or std:

Meta

This bug is not applicable to stable due to its use of -Zbuild-std
