-/// # Macro - Generate Action
-///
-/// When annotating a function with the `#[action_gen]` macro in the following format, it generates boilerplate code for client-server interaction
-///
-/// ```ignore
-/// #[action_gen]
-/// async fn action_name(ctx: ActionContext, argument: YourArgument) -> Result<YourResult, TcpTargetError> {
-///     // Write your client and server logic here

-/// ```
-///
-/// > WARNING:
-/// > For Argument and Result types, the `action_gen` macro only supports types that derive serde's Serialize and Deserialize

-/// ## Generated Code
-///
-/// `action_gen` will generate the following:
-///
-/// 1. Complete implementation of Action<Args, Return>
-/// 2. Process / Register method
-///
-/// ## How to use

-///
-/// A trait used to describe the interaction pattern between client and server
-///
-/// ## Generics
-///
-/// Args: Represents the parameter type required for this action

-///
-/// The above generics must implement serde's Serialize and DeserializeOwned traits,
-/// and must be sendable between threads
-///
-/// ## Implementation
-///

-/// # Macro - ConfigFile
-///
-/// ## Usage
-///
-/// Use `#[derive(ConfigFile)]` to derive the ConfigFile trait for a struct
-///
-/// Specify the default storage path via `#[cfg_file(path = "...")]`
-///
-/// ## About the `cfg_file` attribute macro
-///
-/// Use `#[cfg_file(path = "string")]` to specify the configuration file path
-///
-/// Or use `#[cfg_file(path = constant_expression)]` to specify the configuration file path
-///
-/// ## Path Rules
-///
-/// Paths starting with `"./"`: relative to the current working directory
-///
-/// Other paths: treated as absolute paths
-///
-/// When no path is specified: use the struct name + ".json" as the default filename (e.g., `my_struct.json`)
-///
-/// ## Example
-/// ```ignore
-/// #[derive(ConfigFile)]
-/// #[cfg_file(path = "./config.json")]
-/// struct AppConfig;
-/// ```

-///
-/// Used to implement more convenient persistent storage functionality for structs

-/// This trait requires the struct to implement Default and serde's Serialize and Deserialize traits
-///
-/// ## Implementation
-///
-/// ```ignore

-/// #[derive(Default, Serialize, Deserialize)]
-/// struct YourData;
-///
-/// impl ConfigFile for YourData {

-///     }
-/// }
-/// ```
-///
-/// > **Using derive macro**
