Crate tetsy_memory_db 

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.

Traits

KeyFunction

MaybeDebug

MemTracker

Used to implement incremental evaluation of MallocSizeOf for a collection.

Functions

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.

Type Aliases

DefaultMemTracker

The default memory tracker used by MemoryDB.
