Struct rustc_hir::definitions::DefPathTable
source · [−]pub struct DefPathTable {
index_to_key: IndexVec<DefIndex, DefKey>,
def_path_hashes: IndexVec<DefIndex, DefPathHash>,
def_path_hash_to_index: DefPathHashMap,
}Expand description
The DefPathTable maps DefIndexes to DefKeys and vice versa.
Internally the DefPathTable holds a tree of DefKeys, where each DefKey
stores the DefIndex of its parent.
There is one DefPathTable for each crate.
