Crate memory_db[−][src]

Reference-counted memory-based HashDB implementation.

Structs

HashKey	Key function that only uses the hash
LegacyPrefixedKey	Deprecated 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_key	Deprecated 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.

The default memory tracker used by MemoryDB.
