//! Hungarian (`hu`): the bare-tag alias of [`hu_hu`](crate::hu_hu).
//!
//! `hu` resolves to `hu-HU`, currently the only Hungarian variant this crate
//! implements. It exists so the language is reachable without a region
//! subtag; it is not a claim that `hu-HU` speaks for every Hungarian-speaking
//! region. Cardinal and ordinal are `hu_hu`'s own functions. Currency is the
//! one form a bare tag can't forward untouched: a language has no country to
//! take a default currency from, so [`to_currency`] takes the currency
//! explicitly.
//!
//! ```
//! use n2words::{hu, Currency};
//!
//! assert_eq!(hu::to_cardinal(42)?, "negyvenkettő");
//! assert_eq!(hu::to_ordinal(42)?, "negyvenkettődik");
//! assert_eq!(hu::to_currency(42.5, Currency::HUF)?, "negyvenkettő forint ötven fillér");
//! # Ok::<(), n2words::Error>(())
//! ```
