Struct ReplicaConfig 

pub struct ReplicaConfig {
    pub id: String,
    pub url: String,
    pub role: ReplicaRole,
    pub priority: u32,
    pub weight: u32,
    pub region: Option<String>,
    pub max_lag: Option<Duration>,
}

Configuration for a database replica.

Fields

id: String

Unique identifier for this replica.

url: String

Connection URL.

role: ReplicaRole

Role of this replica.

priority: u32

Priority for failover (higher = preferred).

weight: u32

Weight for load balancing (higher = more traffic).

region: Option<String>

Region/datacenter for locality-aware routing.

max_lag: Option<Duration>

Maximum acceptable replication lag.

Implementations

impl ReplicaConfig

pub fn primary(id: impl Into<String>, url: impl Into<String>) -> Self

Create a primary replica config.

pub fn secondary(id: impl Into<String>, url: impl Into<String>) -> Self

Create a secondary replica config.

pub fn with_region(self, region: impl Into<String>) -> Self

Set region.

pub fn with_weight(self, weight: u32) -> Self

Set weight.

pub fn with_priority(self, priority: u32) -> Self

Set priority.

pub fn with_max_lag(self, lag: Duration) -> Self

Set max lag.

Trait Implementations

impl Clone for ReplicaConfig

fn clone(&self) -> ReplicaConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReplicaConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReplicaConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ReplicaConfig

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
