+    Custom class that encapsulates :tl:`BotResults` providing

+    (such as clicking one of the results to select it)
+
+    Note that this is a list of `InlineResult
+    <telethon.tl.custom.inlineresult.InlineResult>`
+    so you can iterate over it or use indices to
+    access its elements. In addition, it has some
+    attributes.
+
+    Attributes:
+        result (:tl:`BotResults`):
+            The original :tl:`BotResults` object.
+
+        query_id (`int`):
+            The random ID that identifies this query.
+
+        cache_time (`int`):
+            For how long the results should be considered
+            valid. You can call `results_valid` at any
+            moment to determine if the results are still
+            valid or not.
+
+        users (:tl:`User`):
+            The users present in this inline query.
+
+        gallery (`bool`):
+            Whether these results should be presented
+            in a grid (as a gallery of images) or not.
+
+        next_offset (`str`, optional):
+            The string to be used as an offset to get
+            the next chunk of results, if any.
+
+        switch_pm (:tl:`InlineBotSwitchPM`, optional):
+            If presents, the results should show a button to
+            switch to a private conversation with the bot using
+            the text in this object.
