Struct SqlxRoutingConfig 

pub struct SqlxRoutingConfig {
    pub primary: SqlxConfig,
    pub replicas: Vec<SqlxConfig>,
    pub max_replica_lag_secs: Option<u64>,
    pub fallback_to_primary: bool,
}

读写分离配置。未知键直接报错（拼错 replicas 会静默退化成单主库）。

Fields

primary: SqlxConfig

replicas: Vec<SqlxConfig>

max_replica_lag_secs: Option<u64>

副本实测延迟超过它即跳过；None = 不探测。

fallback_to_primary: bool

副本全不可用时是否降级读主，默认 true。
