Trait rustc_ap_rustc_data_structures::stable_hasher::ToStableHashKey[−][src]

pub trait ToStableHashKey<HCX> {
    type KeyType: Ord + Sized + HashStable<HCX>;
    fn to_stable_hash_key(&self, hcx: &HCX) -> Self::KeyType;
}
Expand description

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.

Associated Types

type KeyType: Ord + Sized + HashStable<HCX>[src]

Required methods

fn to_stable_hash_key(&self, hcx: &HCX) -> Self::KeyType[src]
