Expand description

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

Fields

stab_map: FxHashMap<LocalDefId, &'tcx Stability>

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

const_stab_map: FxHashMap<LocalDefId, &'tcx ConstStability>depr_map: FxHashMap<LocalDefId, DeprecationEntry>staged_api: FxHashMap<CrateNum, bool>

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

active_features: FxHashSet<Symbol>

Features enabled for this crate.
