Context

It’s clunky to iterate a cursor via an interface presently because the only way to fetch the current document is via the .Cursor struct member. The workaround is to define a “dummy” type that implements all the methods needed as wrappers around the cursor type. Adding an accessor to the driver’s types simplify that nicely.

It would also make the API a bit more consistent: right now all interaction with those types happens via methods except reading the actual document.

Definition of done

Add an accessor that returns the .Cursor member.

Pitfalls

None that I can see.
