## Union Discrimination

Use the `Type` field to determine which variant is active, then access the corresponding field:

```go lines theme={null}
switch messagesRequestPlugin.Type {
	case components.MessagesRequestPluginTypeAutoRouter:
		// messagesRequestPlugin.AutoRouterPlugin is populated
	case components.MessagesRequestPluginTypeContextCompression:
		// messagesRequestPlugin.ContextCompressionPlugin is populated
	case components.MessagesRequestPluginTypeFileParser:
		// messagesRequestPlugin.FileParserPlugin is populated
	case components.MessagesRequestPluginTypeFusion:
		// messagesRequestPlugin.FusionPlugin is populated
	case components.MessagesRequestPluginTypeModeration:
		// messagesRequestPlugin.ModerationPlugin is populated
	case components.MessagesRequestPluginTypeParetoRouter:
		// messagesRequestPlugin.ParetoRouterPlugin is populated
	case components.MessagesRequestPluginTypeResponseHealing:
		// messagesRequestPlugin.ResponseHealingPlugin is populated
	case components.MessagesRequestPluginTypeWeb:
		// messagesRequestPlugin.WebSearchPlugin is populated
	case components.MessagesRequestPluginTypeWebFetch:
		// messagesRequestPlugin.WebFetchPlugin is populated
}
```
