Please post code as text instead of images, so that it can be copied, pasted, read by screen readers, etc. The forum uses markdown -- encloose code in triple-back-tick fences.

    var router = try server.router(.{});
    router.get("/api/join", join(hub.joinPlayer), .{});

    std.debug.print("Listening on port 3000\n", .{});
    // blocks
    try server.listen();
}

fn join(joinPlayer: fn(Player) anyerror!void) fn(req: *httpz.Request, res: *httpz.Response) anyerror!void {
    return fn(req: *httpz.Request, res: *httpz.Response) anyerror!void {

    };
}

sorry it was for you to see the error too

FWIW, Zig doesn't have closures.

Sorry, the images for me are unreadable.

you need Hub.joinPlayer
