连接池配置构建器
Implementations§
Source§impl PoolConfigBuilder
impl PoolConfigBuilder
Sourcepub fn new() -> PoolConfigBuilder
pub fn new() -> PoolConfigBuilder
创建默认配置构建器
Sourcepub fn max_size(self, size: u32) -> PoolConfigBuilder
pub fn max_size(self, size: u32) -> PoolConfigBuilder
设置最大连接数
Sourcepub fn min_idle(self, count: u32) -> PoolConfigBuilder
pub fn min_idle(self, count: u32) -> PoolConfigBuilder
设置最小空闲连接数
Sourcepub fn acquire_timeout(self, timeout_secs: u64) -> PoolConfigBuilder
pub fn acquire_timeout(self, timeout_secs: u64) -> PoolConfigBuilder
设置获取连接超时（秒）
Sourcepub fn idle_timeout(self, timeout_secs: u64) -> PoolConfigBuilder
pub fn idle_timeout(self, timeout_secs: u64) -> PoolConfigBuilder
设置空闲连接超时（秒）
Sourcepub fn max_lifetime(self, lifetime_secs: u64) -> PoolConfigBuilder
pub fn max_lifetime(self, lifetime_secs: u64) -> PoolConfigBuilder
设置连接最大存活时间（秒）
Sourcepub fn tls(self, tls: TlsConfig) -> PoolConfigBuilder
pub fn tls(self, tls: TlsConfig) -> PoolConfigBuilder
设置 TLS 配置
Sourcepub fn query_timeout(self, timeout: Duration) -> PoolConfigBuilder
pub fn query_timeout(self, timeout: Duration) -> PoolConfigBuilder
设置 SQL 执行超时
Sourcepub fn max_rows(self, max_rows: usize) -> PoolConfigBuilder
pub fn max_rows(self, max_rows: usize) -> PoolConfigBuilder
设置单次查询最大返回行数
Sourcepub fn memory_limit(self, memory_limit: usize) -> PoolConfigBuilder
pub fn memory_limit(self, memory_limit: usize) -> PoolConfigBuilder
设置内存使用上限（字节）
Sourcepub fn on_event(
self,
callback: Arc<dyn Fn(PoolEvent) + Send + Sync>,
) -> PoolConfigBuilder
pub fn on_event( self, callback: Arc<dyn Fn(PoolEvent) + Send + Sync>, ) -> PoolConfigBuilder
设置连接池事件回调
Sourcepub fn test_before_acquire(self, enabled: bool) -> PoolConfigBuilder
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）。
Sourcepub fn prewarm(self, enabled: bool) -> PoolConfigBuilder
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）。
Sourcepub fn build(self) -> Result<PoolConfig, PoolError>
pub fn build(self) -> Result<PoolConfig, PoolError>
构建并校验连接池配置
