Implementations

impl DBOp

pub fn key(&self) -> &[u8]

Returns the key associated with this operation.

pub fn col(&self) -> u32

Returns the column associated with this operation.

Trait Implementations

impl Clone for DBOp

fn clone(&self) -> DBOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl PartialEq for DBOp

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