The formatting trait links are broken (except for Display and UpperExp): https://doc.rust-lang.org/nightly/std/fmt/#formatting-traits

Update: It seems like this was fixed on nighly. But the beta docs still have this issue.

And the link to debug_struct in the core::Debug doc seems broken, too: https://doc.rust-lang.org/nightly/core/fmt/trait.Debug.html#examples (source: https://doc.rust-lang.org/nightly/src/core/fmt/mod.rs.html#359)
