+/**
+ * Event and command declarations for `@entityseven/fivem-rpc`.
+ *
+ * Every interface starts empty: until you declare something in it, the matching
+ * rpc methods accept any name and any arguments. Declare your own by augmenting
+ * this module from any `.d.ts` (or `.ts`) file included in your project:
+ *
+ * @example
+ * // shared/rpc.d.ts
+ * import '@entityseven/fivem-rpc-shared-types'
+ *
+ * declare module '@entityseven/fivem-rpc-shared-types' {
+ * 	interface RPCEvents_ClientServer {
+ * 		// name(arguments): value returned by the listener
+ * 		buyItem(item: string, amount: number): boolean
+ * 	}
+ * 	interface RPCCommands_Server {
+ * 		ban: true
+ * 	}
+ * }
