Expand description

A stability index, giving the stability level for items and methods.

Fields

stab_map: FxHashMap<HirId, &'tcx Stability>
Expand description

This is mostly a cache, except the stabilities of local items are filled by the annotator.

const_stab_map: FxHashMap<HirId, &'tcx ConstStability>depr_map: FxHashMap<HirId, DeprecationEntry>staged_api: FxHashMap<CrateNum, bool>
Expand description

Maps for each crate whether it is part of the staged API.

active_features: FxHashSet<Symbol>
Expand description

Features enabled for this crate.
