Detailed Description

Registry of available event channels.

Tracks all event channels that clients can subscribe to, along with their descriptions. Channels are registered during application initialization when entity-to-event mappings are configured.

Thread Safety:

• All operations are thread-safe.
• Typically, channels are registered at startup before concurrent access.

Usage:

event_channel_registry registry;
 
// Register channels during initialization
registry.register_channel<currency_changed_event>("Currency data modified");
 
// Later, query available channels
auto channels = registry.get_channels();
