All ReQL queries begin from the top-level module.
- Connect - Connect creates a new database session. To view the available connection options see ConnectOpts.
- Close - Close closes the session
- Reconnect - Reconnect closes and re-opens a session.
- Run - Run runs a query using the given connection.
- RunWrite - RunWrite runs a query using the given connection but unlike Run automatically scans the result into a variable of type WriteResponss. This function should be used if you are running a write query (such as Insert, Update, TableCreate, etc...)
- Exec - Exec runs the query but does not return the result.
- NoReplyWait - NoReplyWait ensures that previous queries with the noreply flag have been processed by the server. Note that this guarantee only applies to queries run on the given connection.
- Next - Next retrieves the next document from the result set, blocking if necessary.
- All - All retrieves all documents from the result set into the provided slice and closes the cursor.
- One - One retrieves a single document from the result set into the provided slice and closes the cursor.
- Listen - Listen listens for rows from the database and sends the result onto the given channel
- IsNil - IsNil tests if the current row is nil.
- Err - Err returns nil if no errors happened during iteration, or the actual error otherwise.
- Close - Close closes the cursor, preventing further enumeration.

- GetIntersecting - Get all documents where the given geometry object intersects the geometry object of the requested geospatial index.
- GetNearest - Get all documents where the specified geospatial index is within a certain distance of the specified point (default 100 kilometers).
