Attribute Macro http3_version 

#[http3_version]

Restricts function execution to HTTP/3 requests only.

This attribute macro ensures the decorated function only executes for HTTP/3 protocol requests, the latest version of the HTTP protocol.

Usage

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

#[route("/http3_version")]
struct Http3;

impl ServerHook for Http3 {
    async fn new(_ctx: &Context) -> Self {
        Self
    }

    #[prologue_macros(http3_version, response_body("http3_version"))]
    async fn handle(self, ctx: &Context) {}
}

impl Http3 {
    #[http3_version]
    async fn http3_version_with_ref_self(&self, ctx: &Context) {}
}

#[http3_version]
async fn standalone_http3_version_handler(ctx: &Context) {}

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