Struct rustc::hir::map::definitions::DefKey [−][src]
pub struct DefKey { pub parent: Option<DefIndex>, pub disambiguated_data: DisambiguatedDefPathData, }

A unique identifier that we can use to lookup a definition
precisely. It combines the index of the definition's parent (if
any) with a DisambiguatedDefPathData
.
