Module rustc_passes::diagnostic_items

Detecting diagnostic items.

Diagnostic items are items that are not language-inherent, but can reasonably be expected to exist for diagnostic purposes. This allows diagnostic authors to refer to specific items directly, without having to guess module paths and crates. Examples are:

• Traits like Debug, that have no bearing on language semantics

• Compiler internal types like Ty and TyCtxt
