Trait rustc_data_structures::stable_hasher::ToStableHashKey [−][src]
pub trait ToStableHashKey<HCX> { type KeyType: Ord + Clone + Sized + HashStable<HCX>; fn to_stable_hash_key(&self, hcx: &HCX) -> Self::KeyType; }
Implement this for types that can be turned into stable keys like, for example, for DefId that can be converted to a DefPathHash. This is used for bringing maps into a predictable order before hashing them.
