//! Traits for converting between color spaces.
//!
//! Each color space type, such as [`Rgb`](crate::rgb::Rgb) and
//! [`Hsl`](crate::Hsl), implement a number of conversion traits:
//!
//! * [`FromColor`] - Similar to [`From`], converts from another color space.
//! * [`IntoColor`] - Similar to [`Into`], converts into another color space.
//! * [`FromColorUnclamped`] - The same as [`FromColor`], but the resulting
//! values may be outside the typical bounds.
//! * [`IntoColorUnclamped`] - The same as [`IntoColor`], but the resulting
//! values may be outside the typical bounds.
//!
//! ```
//! use palette::{FromColor, IntoColor, Srgb, Hsl};
//!
//! let rgb = Srgb::new(0.3f32, 0.8, 0.1);
//!
//! let hsl1: Hsl = rgb.into_color();
//! let hsl2 = Hsl::from_color(rgb);
//! ```
//!
//! Most of the color space types can be converted directly to each other, with
//! these traits. If you look at the implemented traits for any color type, you
//! will see a substantial list of `FromColorUnclamped` implementations. There
//! are, however, exceptions and restrictions in some cases:
//!
//! * **It's not always possible to change the component type while
//! converting.** This can only be enabled in specific cases, to allow type
//! inference to work. The input and output component types need to be the
//! same in the general case.
//! * **It's not always possible to change meta types while converting.** Meta
//! types are the additional input types on colors, such as white point or RGB
//! standard. Similar to component types, these are generally restricted to
//! help type inference.
//! * **Some color spaces want specific component types.** For example,
//! [`Xyz`](crate::Xyz) and many other color spaces require real-ish numbers
//! (`f32`, `f64`, etc.).
//! * **Some color spaces want specific meta types.** For example,
//! [`Oklab`](crate::Oklab) requires the white point to be
//! [`D65`](crate::white_point::D65).
//!
//! These limitations are usually the reason for why the compiler gives an error
//! when calling `into_color`, `from_color`, or the corresponding unclamped
//! methods. They are possible to work around by splitting the conversion into
//! multiple steps.
//!
//! # In-place Conversion
//!
//! It's possible for some color spaces to be converted in-place, meaning the
//! destination color will use the memory space of the source color. The
//! requirement for this is that the source and destination color types have the
//! same memory layout. That is, the same component types and the same number of
//! components. This is verified by the [`ArrayCast`](crate::cast::ArrayCast)
//! trait.
//!
//! In-place conversion is done with the [`FromColorMut`] and [`IntoColorMut`]
//! traits, as well as their unclamped counterparts, [`FromColorUnclampedMut`]
//! and [`IntoColorUnclampedMut`]. They work for both single colors and slices
//! of colors.
//!
//! ```
//! use palette::{convert::FromColorMut, Srgb, Hsl, Hwb};
//!
//! let mut rgb_colors: Vec<Srgb<f32>> = vec![/* ... */];
//!
//! {
//! // Creates a scope guard that prevents `rgb_colors` from being modified as RGB.
//! let hsl_colors = <[Hsl]>::from_color_mut(&mut rgb_colors);
//!
//! // The converted colors can be converted again, without keeping the previous guard around.
//! let hwb_colors = hsl_colors.then_into_color_mut::<[Hwb]>();
//!
//! // The colors are automatically converted back to RGB at the end of the scope.
//! // The use of `then_into_color_mut` above makes this conversion a single HWB -> RGB step,
//! // instead of HWB -> HSL -> RGB, since it consumed the HSL guard.
//! }
//! ```
//!
//! # Deriving
//!
//! `FromColorUnclamped` can be derived in a mostly automatic way. The other
//! traits are blanket implemented based on it. The default minimum requirement
//! is to implement `FromColorUnclamped<Xyz>`, but it can also be customized to
//! make use of generics and have other manual implementations.
//!
//! It is also recommended to derive or implement
//! [`WithAlpha`](crate::WithAlpha), to be able to convert between all `Alpha`
//! wrapped color types.
//!
//! ## Configuration Attributes
//!
//! The derives can be configured using one or more `#[palette(...)]`
//! attributes. They can be attached to either the item itself, or to the
//! fields.
//!
//! ```
//! # use palette::rgb::{RgbStandard, RgbSpace};
//! # use palette::convert::FromColorUnclamped;
//! # use palette::{Xyz, stimulus::Stimulus};
//! #
//! #[derive(FromColorUnclamped)]
//! #[palette(
//! component = "T",
//! rgb_standard = "S",
//! )]
//! #[repr(C)]
//! struct ExampleType<S, T> {
//! // ...
//! #[palette(alpha)]
//! alpha: T,
//! standard: std::marker::PhantomData<S>,
//! }
//!
//! # impl<S, T> FromColorUnclamped<Xyz<<S::Space as RgbSpace>::WhitePoint, T>> for ExampleType<S, T>
//! # where
//! # S: RgbStandard,
//! # T: Stimulus,
//! # {
//! # fn from_color_unclamped(color: Xyz<<S::Space as RgbSpace>::WhitePoint, T>) -> Self {
//! # ExampleType {alpha: T::max_intensity(), standard: std::marker::PhantomData}
//! # }
//! # }
//! #
//! # impl<S, T> FromColorUnclamped<ExampleType<S, T>> for Xyz<<S::Space as RgbSpace>::WhitePoint, T>
//! # where
//! # S: RgbStandard,
//! # Self: Default,
//! # {
//! # fn from_color_unclamped(color: ExampleType<S, T>) -> Self {
//! # Xyz::default()
//! # }
//! # }
//! ```
//!
//! ### Item Attributes
//!
//! * `skip_derives(Luma, Rgb)`: No conversion derives will be implemented for
//! these colors. They are instead to be implemented manually, and serve as the
//! basis for the automatic implementations.
//!
//! * `white_point = "some::white_point::Type"`: Sets the white point type that
//! should be used when deriving. The default is `D65`, but it may be any other
//! type, including type parameters.
//!
//! * `component = "some::component::Type"`: Sets the color component type that
//! should be used when deriving. The default is `f32`, but it may be any other
//! type, including type parameters.
//!
//! * `rgb_standard = "some::rgb_standard::Type"`: Sets the RGB standard type
//! that should be used when deriving. The default is to either use `Srgb` or a
//! best effort to convert between standards, but sometimes it has to be set to
//! a specific type. This also accepts type parameters.
//!
//! * `luma_standard = "some::rgb_standard::Type"`: Sets the Luma standard type
//! that should be used when deriving, similar to `rgb_standard`.
//!
//! ### Field Attributes
//!
//! * `alpha`: Specifies field as the color's transparency value.
//!
//! ## Examples
//!
//! Minimum requirements implementation:
//!
//! ```rust
//! use palette::convert::FromColorUnclamped;
//! use palette::{Srgb, Xyz, IntoColor};
//!
//! /// A custom version of Xyz that stores integer values from 0 to 100.
//! #[derive(PartialEq, Debug, FromColorUnclamped)]
//! struct Xyz100 {
//! x: u8,
//! y: u8,
//! z: u8,
//! }
//!
//! // We have to implement at least one "manual" conversion. The default
//! // is to and from `Xyz`, but it can be customized with `skip_derives(...)`.
//! impl FromColorUnclamped<Xyz> for Xyz100 {
//! fn from_color_unclamped(color: Xyz) -> Xyz100 {
//! Xyz100 {
//! x: (color.x * 100.0) as u8,

//! }
//! }
//! }
//!
//! impl FromColorUnclamped<Xyz100> for Xyz {
//! fn from_color_unclamped(color: Xyz100) -> Xyz {
//! Xyz::new(
//! color.x as f32 / 100.0,
//! color.y as f32 / 100.0,
//! color.z as f32 / 100.0,
//! )

//!
//! // Start with an Xyz100 color.
