Struct Publications 

pub struct Publications { /* private fields */ }

Implementations

impl Publications

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn contains(&self, name: &str) -> bool

pub fn get(&self, name: &str) -> Option<&PublicationScope>

v6.1.3 — read a publication’s scope by name. Returns None if no such publication; used by SHOW PUBLICATIONS

• the v6.1.5 publisher-side filter to resolve the per-record OWNER → publication membership question.

pub fn iter(&self) -> impl Iterator<Item = (&String, &PublicationScope)>

Iterate (name, scope) in deterministic (alphabetical) order. The order matters for snapshot byte-stability.

pub fn create( &mut self, name: String, scope: PublicationScope, ) -> Result<(), PublicationError>

PG-incompatible loud error on duplicate (PG silently does nothing on IF NOT EXISTS; bare CREATE PUBLICATION on an existing name DOES error in PG, so we match that).

pub fn drop(&mut self, name: &str) -> bool

Returns whether the publication was actually present. Callers can choose to surface the no-op or stay silent — the v6.1.2 PG-compat policy is silent (no-op), so the engine ignores this return.

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

Format: [u16 num_publications] for each: [u16 name_len][name bytes] [u8 scope_tag] 0 → AllTables (no trailer) 1 → ForTables / 2 → AllTablesExcept [u16 num_tables] for each: [u16 t_len][t bytes]

pub fn deserialize(buf: &[u8]) -> Result<Self, PublicationError>

Trait Implementations

impl Clone for Publications

fn clone(&self) -> Publications

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Publications

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

Formats the value using the given formatter.

impl Default for Publications

fn default() -> Publications

Returns the “default value” for a type.

impl Eq for Publications

impl PartialEq for Publications

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