rdi-core 0.2.30

//! Platform-agnostic animation core for `rusty-desktop-icons`.
//!
//! This crate defines the pure-Rust, cross-platform surface of the project:
//!
//! * Geometry primitives ([`Point`]) and icon identifiers ([`IconId`]).
//! * The [`Curve`] system with two variants ([`BuiltinEasing`] and
//!   [`KeyframeCurve`]) that share a single [`AnimationCurve`] contract.
//! * A [`Duration`] policy that resolves to a concrete `std::time::Duration`
//!   either from a fixed value or from movement distance and speed.
//! * The animation specification types ([`IconAnimationSpec`],
//!   [`AnimationOptions`], [`FolderFlagOp`]).
//! * Error types shared by all backends.
//!
//! The Windows Shell/COM backend, the worker thread, and the Python
//! bindings live in sibling crates and depend on this one.
//!
//! Everything in this crate is `#![forbid(unsafe_code)]` — the only place
//! `unsafe` is allowed is inside `rdi-platform-windows`.
//!
//! ## Quick tour of curves
//!
//! ```
//! use rdi_core::{AnimationCurve, Curve, KeyframeInterp};
//!
//! // Predefined easing.
//! let ease = Curve::ease_in_out();
//! assert!((ease.eval(0.5) - 0.5).abs() < 1e-3);
//!
//! // Data-driven keyframes.
//! let keys = Curve::keyframes(
//!     vec![
//!         rdi_core::Keyframe::new(0.0, 0.0),
//!         rdi_core::Keyframe::new(0.5, 0.9),
//!         rdi_core::Keyframe::new(1.0, 1.0),
//!     ],
//!     KeyframeInterp::Linear,
//! ).unwrap();
//! assert!(keys.eval(0.5) > 0.5);
//!
//! // Function-generated curve — sampled once, then pure data at runtime.
//! let damped = Curve::from_curve_fn(
//!     |t| 1.0 - (1.0 - t).powi(3),
//!     32,
//!     KeyframeInterp::Linear,
//! ).unwrap();
//! assert!(damped.eval(1.0) > 0.9);
//! ```
