Source 
pub struct StdHashKey;
Expand description

Hashing strategy that delegates to the standard Hash trait.

Trait Implementations§

Source§

impl<T: Hash> CacheKey<T> for StdHashKey

Source§

fn node_hash(term: &T) -> u64

Compute a level-independent hash for term.
Source§

fn combine(node_hash: u64, level: usize) -> u64

Combine a node hash with a rule-group level to produce a cache key.
Source§

fn hash(term: &T, level: usize) -> u64

Compute a cache key for term at the given rule application level.
Source§

fn invalidate(_node: &T)

Invalidate any internally cached hash for the given node. The default is a no-op (used by StdHashKey).
Source§

fn invalidate_subtree(_node: &T)

Invalidate cached hashes for the given node and all its descendants. The default is a no-op (used by StdHashKey).
