Struct rustc_hir::def_id::StableCrateId[−][src]

pub struct StableCrateId(u64);

A StableCrateId is a 64 bit hash of (crate-name, crate-disambiguator). It is to CrateNum what DefPathHash is to DefId. It is stable across compilation sessions.

Since the ID is a hash value there is a (very small) chance that two crates end up with the same StableCrateId. The compiler will check for such collisions when loading crates and abort compilation in order to avoid further trouble.
