#![deny(rustdoc::broken_intra_doc_links)]

//! This module provides traits, error types, and implementations for various
//! hyperbolic functions and their inverses (e.g., `sinh`, `cosh`, `asinh`, `acosh`).
//!
//! It defines a set of traits (e.g., [`SinH`], [`ACosH`], etc.) for standard
//! hyperbolic operations. These traits are implemented for [`f64`], [`num::Complex<f64>`],
//! [`RealValidated`](crate::RealValidated), [`ComplexValidated`](crate::ComplexValidated),
//! and can be extended to other numeric types satisfying the [`RealScalar`](crate::RealScalar) or
//! [`ComplexScalar`](crate::ComplexScalar) traits.
//!
//! A comprehensive error handling system is in place, utilizing specific input
//! error enums (e.g., [`ACosHInputErrors`], [`TanHComplexInputErrors`], etc.) and
//! general function error type aliases (e.g., [`SinHErrors`], [`ACosHErrors`], etc.)
//! built upon the [`FunctionErrors`] struct. This allows for granular reporting
//! of issues such as invalid arguments (NaN, infinity) or out-of-domain values.
//!
//! The design emphasizes robustness through strict validation of inputs and outputs,
//! primarily using the [`StrictFinitePolicy`].

/// A convenience trait that aggregates the standard hyperbolic functions and their inverses.
///
/// This trait serves as a shorthand for requiring a type to implement all the fundamental
/// hyperbolic operations:
/// - [`SinH`] and [`ASinH`]
/// - [`CosH`] and [`ACosH`]
/// - [`TanH`] and [`ATanH`]
///
/// It is primarily used as a super-trait for [`FpScalar`](crate::FpScalar) to simplify trait bounds
/// and ensure that any scalar type in the library provides a comprehensive set of hyperbolic
/// capabilities. By using `HyperbolicFunctions` as a bound, you can write generic functions that
/// utilize any of its constituent trait methods.
///
/// # Examples
///
/// ```
/// use num_valid::functions::{HyperbolicFunctions, Abs};
/// use std::ops::{Mul, Sub};
///
/// // A generic function that verifies the identity cosh(x)^2 - sinh(x)^2 = 1.
/// // We bound T by HyperbolicFunctions, Clone, and arithmetic ops.
/// fn verify_hyperbolic_identity<T>(x: T) -> T
/// where
///     T: HyperbolicFunctions + Clone + Sub<Output = T> + Mul<Output = T>,
/// {
///     let cosh_x = x.clone().cosh();
///     let sinh_x = x.sinh();
///     // This works because FpScalar requires the necessary arithmetic traits.
///     cosh_x.clone() * cosh_x - sinh_x.clone() * sinh_x
/// }
///
/// let value = 0.5f64;
/// let identity = verify_hyperbolic_identity(value);
///
/// // The result should be very close to 1.0.
/// // We use the Abs trait for comparison.
/// assert!((identity - 1.0).abs() < 1e-12);
/// ```
