bitcoinleveldb-slice vs bitcoinleveldb-cache vs bitcoinleveldb-status

Low-level, non-owning byte Slice type for LevelDB-style storage in bitcoin-rs, providing pointer-based views, prefix operations, lexicographic comparison, and FFI-friendly interoperability without copying.

Low-level, Bitcoin Core–compatible in-memory cache for LevelDB-style storage, providing capacity-bounded LRU eviction, explicit charge-based memory accounting, and opaque pointer values with custom deleters for FFI-heavy systems.

C++-compatible LevelDB-style `Status` and `StatusCode` implementation used by bitcoin-rs for precise error classification, binary layout compatibility, and FFI with the Bitcoin Core LevelDB fork.
