Struct CustomAsyncValidator 

pub struct CustomAsyncValidator<F> { /* private fields */ }

Wraps an async closure as an AsyncValidator — the escape hatch for checks this crate can’t sensibly hardcode. Return Ok(()) to pass, Err(reason) to fail.

let no_hallucination = CustomAsyncValidator::new("grounded_in_context", |text| async move {
    if ask_llm_judge(&text).await { Ok(()) } else { Err("not grounded in retrieved context".into()) }
});
