pub struct AnyPool { /* private fields */ }Expand description
后端无关的连接工厂
Implementations§
Source§impl AnyPool
impl AnyPool
Sourcepub async fn connect(dsn: &str) -> Result<Self, DbError>
pub async fn connect(dsn: &str) -> Result<Self, DbError>
连接数据库，根据 DSN 自动识别后端
§错误
- DSN scheme 不识别 →
DbError::ConnectionRefused - 连接失败 →
DbError::ConnectionError - Oracle/MSSQL 后端未启用对应 feature →
DbError::ConnectionRefused含提示
Sourcepub fn from_factory(
backend: AnyBackend,
factory: Arc<dyn ConnectionFactory>,
) -> Self
pub fn from_factory( backend: AnyBackend, factory: Arc<dyn ConnectionFactory>, ) -> Self
从已有的连接工厂构造
Sourcepub fn backend(&self) -> AnyBackend
pub fn backend(&self) -> AnyBackend
获取后端类型
Sourcepub fn dialect(&self) -> Box<dyn Dialect>
pub fn dialect(&self) -> Box<dyn Dialect>
返回对应后端的 Dialect 实例（v2.2.0 新增）
委托 AnyBackend::dialect()，根据后端自动选择方言。
Sourcepub async fn create(&self) -> Result<AnyConnection, DbError>
pub async fn create(&self) -> Result<AnyConnection, DbError>
创建一个新连接
