pub struct StableCrateId(pub(crate) Hash64);Expand description
A StableCrateId is a 64-bit hash of a crate name, together with all
-Cmetadata arguments, and some other data. 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 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.
For more information on the possibility of hash collisions in rustc,
see the discussion in DefId.
