Struct AnyPool

Source

pub struct AnyPool { /* private fields */ }

Expand description

后端无关的连接工厂

Implementations§

Source §

impl AnyPool

Source

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

Source

pub fn from_factory( backend: AnyBackend, factory: Arc<dyn ConnectionFactory>, ) -> Self

从已有的连接工厂构造

Source

pub fn backend(&self) -> AnyBackend

获取后端类型

Source

pub async fn create(&self) -> Result<AnyConnection, DbError>

创建一个新连接
