Implementations

impl WalEntry

pub fn put(sequence: u64, key: Key, value: CipherBlob) -> Self

Create a Put entry

pub fn delete(sequence: u64, key: Key) -> Self

Create a Delete entry

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

Verify checksum

pub fn encode(&self) -> Vec<u8>

Encode entry to bytes

pub fn decode(bytes: &[u8]) -> Result<Self>

Decode entry from bytes

Trait Implementations

impl Clone for WalEntry

fn clone(&self) -> WalEntry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WalEntry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for WalEntry

fn eq(&self, other: &WalEntry) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
