Expand description

Reference-counted memory-based HashDB implementation.

Structs§

HashKey: Key function that only uses the hash
LegacyPrefixedKeyDeprecated: Key function that concatenates prefix and hash. This is doing useless computation and should only be used for legacy purpose. It shall be remove in the future.
MemCounter: MemTracker implementation for types which implement MallocSizeOf.
MemoryDB: Reference-counted memory-based HashDB implementation.
NoopTracker: No-op MemTracker implementation for when we want to construct a MemoryDB instance that does not track memory usage.
PrefixedKey: Key function that concatenates prefix and hash.

KeyFunction
MaybeDebug
MemTracker: Used to implement incremental evaluation of MallocSizeOf for a collection.

hash_key: Make database key from hash only.
legacy_prefixed_keyDeprecated: Legacy method for db using previous version of prefix encoding. Only for trie radix 16 trie.
prefixed_key: Derive a database key from hash value of the node (key) and the node prefix.
