Crate corium_log 

Durable append-only transaction logs with replay and range scans.

Structs

FileLog

Filesystem append log. Each append is flushed and fsynced before returning.

LogCipher

Encrypts and decrypts transaction-log record payloads for one database.

MemLogRegistry

Process-shared registry of in-memory transaction logs, keyed by database name. It plays the role the log directory plays for VersionedLog: opening the same name (under any lease version) reaches the same records, so a mem-backed transactor recovers state across open/create calls within one process. Cloning a registry shares its storage.

MemVersionedLog

An in-memory transaction log with the same per-lease-version merge semantics as VersionedLog, obtained from a MemLogRegistry. Used by the mem-backed transactor: fully ephemeral, confined to one process.

MemoryLog

In-memory log implementation.

NativeVersionedLog

Versioned transaction log backed by a native key/value-style store.

TxRecord

One committed transaction record.

VersionedLog

A transaction log split into per-lease-version files for HA append isolation (see docs/design/log-and-transactor.md).

Enums

LogError

Log errors.

Traits

NativeLogStorage

Asynchronous object store for transaction-log records.

TransactionLog

Common transaction log interface.

Functions

append_framed_record

Appends one checksummed, length-prefixed cleartext record to out.

append_framed_record_sealed

Appends one checksummed, length-prefixed record to out, sealed under cipher when one is configured.

decode_framed_records

Decodes all cleartext records from a framed byte slice.

decode_framed_records_sealed

Decodes all records from a framed byte slice, opening sealed payloads with cipher.
