Struct rustc_ap_rustc_span::def_id::LocalDefId

pub struct LocalDefId(_);

A LocalDefId is equivalent to a DefId with krate == LOCAL_CRATE. Since we encode this information in the type, we can ensure at compile time that no DefIds from upstream crates get thrown into the mix. There are quite a few cases where we know that only DefIds from the local crate are expected and a DefId from a different crate would signify a bug somewhere. This is when LocalDefId comes in handy.
