Struct rustc_hir::definitions::DefKey
source · 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>
The parent path.
disambiguated_data: DisambiguatedDefPathData
The identifier of this node.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
