 Before 0.11, the driver couldn't do this kind of type checking. For example, in the case of non-batch queries, the only information about the user data it has is that it implements `ValueList` - defined as follows:
 
 ```rust
+# extern crate scylla;
+# extern crate bytes;
+# use scylla::frame::value::{SerializedResult, SerializeValuesError};
+# use bytes::BufMut;

 pub trait ValueList {

 In order to bring the old behavior to the new macros (the only difference being type checking which cannot be disabled right now) you can configure it using attributes, as shown in the snippet below:
 
 ```rust

 // The exact same attributes apply to the `SerializeRow` macro and their
 // effect is completely analogous.
