[−][src]Trait mobc::Manager
A trait which provides connection-specific functionality.
Associated Types
type Connection: Send + 'static
The connection type this manager deals with.
type Error: Send + Sync + 'static
The error type returned by Connection
s.
Required methods
fn connect<'life0, 'async_trait>(
&'life0 self
) -> Pin<Box<dyn Future<Output = Result<Self::Connection, Self::Error>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
&'life0 self
) -> Pin<Box<dyn Future<Output = Result<Self::Connection, Self::Error>> + Send + 'async_trait>> where
'life0: 'async_trait,
Self: 'async_trait,
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,
&'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.
A standard implementation would check if a simple query like SELECT 1
succeeds.
Provided methods
fn spawn_task<T>(&self, task: T) where
T: Future + Send + 'static,
T::Output: Send + 'static,
T: Future + Send + 'static,
T::Output: Send + 'static,
Spawns a new asynchronous task.
