Enum ReplicaIdentity 

pub enum ReplicaIdentity {
    Default,
    Nothing,
    Full,
    Index,
}

PostgreSQL replica identity settings

Variants

Default

Default replica identity (primary key)

Nothing

No replica identity

Full

Full replica identity (all columns)

Index

Index-based replica identity

Implementations

impl ReplicaIdentity

pub fn from_byte(byte: u8) -> Option<ReplicaIdentity>

Create replica identity from byte

Converts a PostgreSQL replica identity byte code to the enum variant.

Arguments

• byte - Single byte representing replica identity (‘d’, ‘n’, ‘f’, or ‘i’)

Returns

• Some(ReplicaIdentity) if the byte is valid
• None if the byte is unrecognized

Example

use pg_walstream::ReplicaIdentity;

assert_eq!(ReplicaIdentity::from_byte(b'd'), Some(ReplicaIdentity::Default));
assert_eq!(ReplicaIdentity::from_byte(b'f'), Some(ReplicaIdentity::Full));
assert_eq!(ReplicaIdentity::from_byte(b'x'), None);

pub fn to_byte(&self) -> u8

Convert to byte representation

Converts the replica identity enum to PostgreSQL’s single-byte format.

Returns

Single byte representing the replica identity:

• b'd' - Default (primary key)
• b'n' - Nothing (no replica identity)
• b'f' - Full (all columns)
• b'i' - Index (specific index)

Example

use pg_walstream::ReplicaIdentity;

assert_eq!(ReplicaIdentity::Default.to_byte(), b'd');
assert_eq!(ReplicaIdentity::Full.to_byte(), b'f');

Trait Implementations

impl Clone for ReplicaIdentity

fn clone(&self) -> ReplicaIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReplicaIdentity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReplicaIdentity

fn deserialize<__D>( __deserializer: __D, ) -> Result<ReplicaIdentity, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ReplicaIdentity

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

impl Serialize for ReplicaIdentity

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
