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 DefIndex
es to DefKey
s and vice versa.
Internally the DefPathTable
holds a tree of DefKey
s, where each DefKey
stores the DefIndex
of its parent.
There is one DefPathTable
for each crate.

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.
