Expand description
A trait which provides connection-specific functionality.
Associated Types
type Connection: Send + 'static
type Connection: Send + 'static
The connection type this manager deals with.
Required methods
Attempts to create a new connection.
fn check<'life0, 'async_trait>(
&'life0 self,
conn: Self::Connection
) -> Pin<Box<dyn Future<Output = Result<Self::Connection, Self::Error>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
fn check<'life0, 'async_trait>(
&'life0 self,
conn: Self::Connection
) -> Pin<Box<dyn Future<Output = Result<Self::Connection, Self::Error>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
Determines if the connection is still connected to the database when check-out.
A standard implementation would check if a simple query like SELECT 1
succeeds.
Provided methods
Spawns a new asynchronous task.
fn validate(&self, _conn: &mut Self::Connection) -> bool
fn validate(&self, _conn: &mut Self::Connection) -> bool
Quickly determines a connection is still valid when check-in.
