+/// # Trait - Action<Args, Return>
+///
+/// A trait used to describe the interaction pattern between client and server
+///
+/// ## Generics
+///
+/// Args: Represents the parameter type required for this action
+///
+/// Return: Represents the return type of this action
+///
+/// The above generics must implement serde's Serialize and DeserializeOwned traits,
+/// and must be sendable between threads
+///
+/// ## Implementation
+///
+/// ```ignore
+/// pub trait Action<Args, Return>
+/// where
+///     Args: Serialize + DeserializeOwned + Send,
+///     Return: Serialize + DeserializeOwned + Send,
+/// {
+///     /// Name, used to inform the server which action to execute
+///     fn action_name() -> &'static str;
+///
+///     /// Whether it's a local Action, used to inform the system if it only runs locally
+///     fn is_remote_action() -> bool;
+///
+///     /// Action processing logic
+///     fn process(
+///         context: ActionContext,
+///         args: Args,
+///     ) -> impl std::future::Future<Output = Result<Return, TcpTargetError>> + Send;
