Struct Changeset 

pub struct Changeset {
    pub tables: Vec<TableChangeset>,
}

A complete changeset covering one or more tables.

Fields

tables: Vec<TableChangeset>

Implementations

impl Changeset

pub fn new() -> Self

Create an empty changeset.

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

Encode the entire changeset in binary format.

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

Encode the entire changeset as a patchset (compact form).

pub fn decode(data: &[u8]) -> Option<Self>

Decode a changeset from its binary representation.

pub fn invert(&self) -> Self

Invert the changeset: every INSERT becomes DELETE, every DELETE becomes INSERT, every UPDATE swaps old and new values.

pub fn concat(&mut self, other: &Self)

Concatenate another changeset onto this one.

Trait Implementations

impl Clone for Changeset

fn clone(&self) -> Changeset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Changeset

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

Formats the value using the given formatter.

impl Default for Changeset

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Changeset

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