prismatica 0.3.1

//! Termion integration.
//!
//! Provides bidirectional conversion between [`Color`](crate::Color)
//! and [`termion::color::Rgb`].
//!
//! Both types store u8 RGB channels, so the conversion is lossless.
//!
//! **Note:** termion only supports Unix platforms.
//!
//! # Examples
//!
//! ```ignore
//! use prismatica::crameri::BATLOW;
//!
//! let color = BATLOW.eval(0.5);
//! let rgb: termion::color::Rgb = color.into();
//! let back: prismatica::Color = rgb.into();
//! assert_eq!(color, back); // lossless u8 roundtrip
//! ```
