Module feed_channels

A central container for all inter-thread communication channels used by the Feed module.

This module defines the FeedChannels struct, which acts as a dedicated “switchboard” for the Feed thread. Its primary purpose is to aggregate all the mpsc::channel senders and receivers that the Feed thread needs to communicate with other concurrent parts of the application, such as the RelayManager, SignalHandler, and the IPC Messaging thread.

Key Components

• FeedChannels Struct: A simple container struct that explicitly declares all the communication dependencies of the Feed thread.

• Helper Methods: Provides convenient wrapper methods like send_to_relay_manager() and receive_from_relay_manager(). These methods offer a clean, consistent API for channel operations and abstract away the direct use of the sender/receiver fields.

Design and Architecture

The FeedChannels struct is a key part of the application’s inter-thread communication strategy, promoting clean and decoupled code.

• Centralization: By gathering all necessary channels into a single struct, it provides a clear and explicit declaration of the Feed thread’s communication dependencies. This makes the overall architecture easier to reason about.

• Decoupling: The main Feed thread logic doesn’t need to manage a list of individual channels. It just needs this struct, which it can use to send and receive messages. This separates the core control logic from the communication infrastructure.

• Testability: The struct’s channels can be used by mock implementation during unit testing, allowing for isolated testing of the Feed thread’s logic without needing to run the entire application.
