Attribute Macro send_once 

#[send_once]

Sends the complete response exactly once 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.

Usage

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

#[route("/send_once")]
struct SendOnceTest;

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

    #[epilogue_macros(send_once)]
    async fn handle(self, ctx: &Context) {}
}

impl SendOnceTest {
    #[send_once]
    async fn send_once_with_ref_self(&self, ctx: &Context) {}
}

#[send_once]
async fn standalone_send_once_handler(ctx: &Context) {}

The macro takes no parameters and should be applied directly to async functions that accept a &Context parameter.
