+The PRAW library's data retrieval architecture is primarily composed of two distinct but complementary patterns: listing generation and stream generation. The ListingGenerator forms the backbone for paginated data retrieval, efficiently fetching and iterating through large datasets from the Reddit API. This core functionality is extended and specialized by BaseListingMixin, SubredditListingMixin, and RedditorListingMixin, which provide context-specific listing capabilities for general, subreddit, and redditor content, respectively. For real-time data, the StreamGenerator (implemented as stream_generator utility) offers a robust mechanism for continuous data delivery, handling deduplication and rate limiting.

This dual approach ensures comprehensive and efficient access to both historical and real-time Reddit data.

+
+RedditorsStream
+^^^^^^^^^^^^^^^
+
+Represents the `stream` method within the `Redditors` class, acting as an entry point for initiating and managing a continuous stream of new redditors as they are created or become active. It provides a high-level interface for accessing real-time user data by leveraging the `stream_generator` utility.
