struct CachedValueHasher

Hasher for CachedValue: the node’s canonical hash, i.e. byte-identical to TreeNodeHasher.

Public Types

using is_transparent = void

Public Functions

inline std::size_t operator()(CachedValue<Node> const &cv) const

inline std::size_t operator()(Node const &n) const

Heterogeneous overload: probe the map with a bare node, which need not be one of the keyed nodes (e.g. a structurally equal node of another tree). The hash is the node’s canonical hash either way.
