Trait Implementations

impl Connection for ConnectionBox

fn get_rows( &mut self, sql: &str, params: Vec<Value> ) -> BoxFuture<'_, Result<Vec<Box<dyn Row>>, Error>>

Execute a query that is expected to return a result set, such as a SELECT statement

fn exec( &mut self, sql: &str, params: Vec<Value> ) -> BoxFuture<'_, Result<ExecResult, Error>>

Execute a query that is expected to update some rows.

fn close(&mut self) -> BoxFuture<'_, Result<(), Error>>

close connection Normally conn is dropped when the link is dropped, but it is recommended to actively close this function so that the database does not report errors. If &mut self is not satisfied close, when you need mut self, It is recommended to use Option and then call take to take ownership and then if let Some(v) = self.inner.take() {v.lose ().await; }

fn ping(&mut self) -> BoxFuture<'_, Result<(), Error>>

ping

an translation impl begin

fn commit(&mut self) -> BoxFuture<'_, Result<(), Error>>

fn rollback(&mut self) -> BoxFuture<'_, Result<(), Error>>

an translation impl rollback

fn get_values( &mut self, sql: &str, params: Vec<Value> ) -> BoxFuture<'_, Result<Vec<Value>, Error>>

Execute a query that is expected to return a result set, such as a SELECT statement
