pub trait UpdateAndFetchResults<Changes, Output>: Connection {
    fn update_and_fetch(&self, changeset: Changes) -> QueryResult<Output>;
}
Expand description

A trait defining how to update a record and fetch the updated entry on a certain backend.

The only case where it is required to work with this trait is while implementing a new connection type. Otherwise use SaveChangesDsl

For implementing this trait for a custom backend:

  • The Changes generic parameter represents the changeset that should be stored
  • The Output generic parameter represents the type of the response.

Required methods

See the traits documentation.
