Struct rustc_middle::middle::stability::Index

pub struct Index<'tcx> {
    pub stab_map: FxHashMap<HirId, &'tcx Stability>,
    pub const_stab_map: FxHashMap<HirId, &'tcx ConstStability>,
    pub depr_map: FxHashMap<HirId, DeprecationEntry>,
    pub staged_api: FxHashMap<CrateNum, bool>,
    pub active_features: FxHashSet<Symbol>,
}

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

Fields

stab_map: FxHashMap<HirId, &'tcx Stability>

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>

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

active_features: FxHashSet<Symbol>

Features enabled for this crate.

Implementations

impl<'tcx> Index<'tcx>

)

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
