    VecDel {

}

A mutation record that can be logged to a WAL.

This is a core-level type that mirrors the storage layer’s WalEntry without depending on the storage crate.

Trait Implementations

impl Clone for WalRecord

fn clone(&self) -> WalRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WalRecord

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

Formats the value using the given formatter.

impl PartialEq for WalRecord

fn eq(&self, other: &WalRecord) -> 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.
