query returns only row data, without a query plan or execution statistics.

pub async fn query_with_option(
    &mut self,
    statement: Statement,
    options: QueryOptions
) -> Result<RowIterator<'_>, Status>

query executes a query against the database. It returns a RowIterator for retrieving the resulting rows.

query returns only row data, without a query plan or execution statistics.

    &mut self,
    table: T,
    columns: Vec<C>,
    key_set: K
) -> Result<RowIterator<'_>, Status> where
    T: Into<String>,
    C: Into<String>,
    K: Into<KeySet>, 

read returns a RowIterator for reading multiple rows from the database.
