Trait odbc_iter::TryFromRow

pub trait TryFromRow<C: Configuration>: Sized {
    type Error: Error + 'static;
    fn try_from_row<'r, 's, 'c, S>(
        row: Row<'r, 's, 'c, S, C>
    ) -> Result<Self, Self::Error>;
}

This traits allow for conversion of Row type representing ODBC cursor used internally by ResultSet iterator to any other type returned as Item that implements it.

This trait is implemented for Rust tuple type enabling conversion of rows to tuples of types implementing TryFromValue. Also this trait implementation allows to convert single column rows to types implementing TryFromColumn.

This trait can be implemented for custom objects. This will enable them to be queried directly from database as Item of ResultSet iterator.
