Trait tarantool::net_box::ConnTriggers

pub trait ConnTriggers {
    // Required methods
    fn on_connect(&self, conn: &Conn) -> Result<(), Error>;
    fn on_disconnect(&self);
    fn on_schema_reload(&self, conn: &Conn);
}

Provides triggers for connect, disconnect and schema reload events.

Required Methods

fn on_connect(&self, conn: &Conn) -> Result<(), Error>

Defines a trigger for execution when a new connection is established, and authentication and schema fetch are completed due to an event such as connect.

If the trigger execution fails and an exception happens, the connection’s state changes to error. In this case, the connection is terminated.

fn on_disconnect(&self)

Define a trigger for execution after a connection is closed.

fn on_schema_reload(&self, conn: &Conn)

Define a trigger executed when some operation has been performed on the remote server after schema has been updated. So, if a server request fails due to a schema version mismatch error, schema reload is triggered.
