Attribute Macro send_once_with_data 

#[send_once_with_data]

Sends the complete response exactly once with data after function execution.

This attribute macro ensures that the response is sent exactly once to the client, preventing multiple response transmissions for single-use scenarios, with the specified data.

Usage

use hyperlane::*;
use hyperlane_macros::*;

#[route("/send_once_with_data")]
struct SendOnceWithData;

impl ServerHook for SendOnceWithData {
    async fn new(_ctx: &Context) -> Self {
        Self
    }

    #[epilogue_macros(send_once_with_data("One-time response"))]
    async fn handle(self, ctx: &Context) {}
}

The macro accepts data to send and should be applied to async functions that accept a &Context parameter.
