cursor property
Cursor is the seq to send as after on the next poll — the highest seq in this page, or the cursor sent in when the page is empty.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? cursor;
