Struct rustc_hir::definitions::DefPathTable

source ·
pub struct DefPathTable {
    stable_crate_id: StableCrateId,
    index_to_key: IndexVec<DefIndex, DefKey>,
    def_path_hashes: IndexVec<DefIndex, Hash64>,
    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.
