Function tokio_postgres::cancel_query

pub fn cancel_query<T>(
    params: T, 
    tls_mode: TlsMode, 
    cancel_data: CancelData, 
    handle: &Handle
) -> BoxFuture<(), ConnectError> where
    T: IntoConnectParams, 

Attempts to cancel an in-progress query.

The backend provides no information about whether a cancellation attempt was successful or not. An error will only be returned if the driver was unable to connect to the database.

A CancelData object can be created via Connection::cancel_data. The object can cancel any query made on that connection.

Only the host and port of the connection info are used. See Connection::connect for details of the params argument.
