Attribute Macro reject_host 

#[reject_host]

Reject requests that have no host header.

This attribute macro ensures the decorated function only executes when the incoming request has a host header present. Requests without a host header will be filtered out.

Usage

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

#[reject_host("localhost")]
async fn handle_with_host(ctx: Context) {
    // Function body for requests with host header
}

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