pub struct PoolConfigBuilder { /* private fields */ }

Implementations

impl PoolConfigBuilder

pub fn new() -> PoolConfigBuilder

pub fn max_size(self, size: u32) -> PoolConfigBuilder

pub fn min_idle(self, count: u32) -> PoolConfigBuilder

pub fn acquire_timeout(self, timeout_secs: u64) -> PoolConfigBuilder

pub fn idle_timeout(self, timeout_secs: u64) -> PoolConfigBuilder

pub fn max_lifetime(self, lifetime_secs: u64) -> PoolConfigBuilder

pub fn tls(self, tls: TlsConfig) -> PoolConfigBuilder

设置 TLS 配置

pub fn query_timeout(self, timeout: Duration) -> PoolConfigBuilder

设置 SQL 执行超时

pub fn max_rows(self, max_rows: usize) -> PoolConfigBuilder

设置单次查询最大返回行数

pub fn memory_limit(self, memory_limit: usize) -> PoolConfigBuilder

设置内存使用上限（字节）

pub fn on_event( self, callback: Arc<dyn Fn(PoolEvent) + Send + Sync>, ) -> PoolConfigBuilder

设置连接池事件回调

pub fn test_before_acquire(self, enabled: bool) -> PoolConfigBuilder

设置 acquire 时是否执行 ping 验证连接存活（P1-1）

开启后，从空闲队列取出的连接会先执行 ping() 验证网络连通性。 默认关闭（仅做 is_connected() 内存检查）。

pub fn prewarm(self, enabled: bool) -> PoolConfigBuilder

设置连接池预热（P2-1）

启用后池创建时立即建立 min_idle 个连接，减少首次查询延迟。 默认关闭（冷启动）。

pub fn build(self) -> Result<PoolConfig, PoolError>
