Enum ReplicationMode 

pub enum ReplicationMode {
    Async,
    SemiSync,
    Sync,
}

Replication mode controlling write acknowledgement behavior.

Variants

Async

Leader returns 200 immediately after local WAL write (default).

SemiSync

Leader waits for at least 1 follower ACK before returning 200. Falls back to async (with warning) if ACK timeout expires.

Sync

Leader waits for ALL followers to ACK before returning 200.

Implementations

impl ReplicationMode

pub fn from_str_value(s: &str) -> Self

Parse from environment variable value.

Trait Implementations

impl Clone for ReplicationMode

fn clone(&self) -> ReplicationMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReplicationMode

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

Formats the value using the given formatter.

impl Display for ReplicationMode

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

Formats the value using the given formatter.

impl PartialEq for ReplicationMode

fn eq(&self, other: &ReplicationMode) -> 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 ReplicationMode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ReplicationMode
