Struct WalRecord 

pub struct WalRecord {
    pub header: RecordHeader,
    pub payload: Vec<u8>,
}

A complete WAL record: header + payload.

Fields

header: RecordHeader

payload: Vec<u8>

Implementations

impl WalRecord

pub fn new( record_type: u16, lsn: u64, tenant_id: u32, vshard_id: u16, payload: Vec<u8>, encryption_key: Option<&WalEncryptionKey>, ) -> Result<Self>

Create a new WAL record with computed CRC32C.

If encryption_key is provided, the payload is encrypted before CRC computation. The ciphertext includes a 16-byte auth tag.

pub fn decrypt_payload( &self, encryption_key: Option<&WalEncryptionKey>, ) -> Result<Vec<u8>>

Decrypt the payload if the record is encrypted.

Returns the plaintext payload. If not encrypted, returns the payload as-is.

pub fn decrypt_payload_ring(&self, ring: Option<&KeyRing>) -> Result<Vec<u8>>

Decrypt the payload using a key ring (supports dual-key rotation).

Tries the current key first, then falls back to the previous key. Returns the plaintext payload. If not encrypted, returns the payload as-is.

pub fn is_encrypted(&self) -> bool

Whether this record’s payload is encrypted.

pub fn logical_record_type(&self) -> u16

Get the logical record type (with encryption flag stripped).

pub fn verify_checksum(&self) -> Result<()>

Verify the CRC32C checksum.

pub fn wire_size(&self) -> usize

Total size on disk: header + payload.
