Struct rustc_hir::definitions::DefKey[−][src]

pub struct DefKey {
    pub parent: Option<DefIndex>,
    pub disambiguated_data: DisambiguatedDefPathData,
}
Expand description

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.

Fields

parent: Option<DefIndex>
Expand description

The parent path.

disambiguated_data: DisambiguatedDefPathData
Expand description

The identifier of this node.
