metas: IndexVec<CrateNum, Option<Lrc<CrateMetadata>>>injected_panic_runtime: Option<CrateNum>allocator_kind: Option<AllocatorKind>

This crate needs an allocator and either provides it itself, or finds it in a dependency. If the above is true, then this field denotes the kind of the found allocator.

has_global_allocator: bool

This crate has a #[global_allocator] item.

stable_crate_ids: FxHashMap<StableCrateId, CrateNum>

This map is used to verify we get no hash conflicts between StableCrateId values.

unused_externs: Vec<Symbol>

Unused externs of the crate


Only public-facing way to traverse all the definitions in a non-local crate. Critically useful for this third-party project: See for context.
