leptos-motion 0.9.0

//! # Leptos Motion
//!
//! A comprehensive animation library for Leptos with Framer Motion-inspired API.
//!
//! ## Features
//!
//! - **Declarative animations** with Motion-style API
//! - **Hardware acceleration** via Web Animations API with RAF fallback
//! - **Gesture support** for drag, hover, tap, and more
//! - **Layout animations** using FLIP technique
//! - **Scroll animations** with intersection observers
//! - **Type safety** with full Rust compile-time validation
//! - **High performance** targeting 60fps for 100+ concurrent animations
//! - **Animation presets** for common patterns
//! - **Keyframe animations** for complex multi-step animations
//! - **Variants** for named animation states
//!
//! ## Quick Start
//!
//! ```rust,no_run
//! use leptos::*;
//! use leptos_motion::*;
//! use std::collections::HashMap;
//!
//! #[component]
//! fn App() -> impl IntoView {
//!     let mut initial = HashMap::new();
//!     initial.insert("opacity".to_string(), AnimationValue::Number(0.0));
//!     initial.insert("scale".to_string(), AnimationValue::Number(0.5));
//!
//!     let mut animate = HashMap::new();
//!     animate.insert("opacity".to_string(), AnimationValue::Number(1.0));
//!     animate.insert("scale".to_string(), AnimationValue::Number(1.0));
//!
//!     view! {
//!         <MotionDiv
//!             class="my-element".to_string()
//!             initial=initial
//!             animate=animate
//!             transition=Transition {
//!                 duration: Some(0.5),
//!                 ease: Easing::EaseOut,
//!                 delay: None,
//!                 repeat: RepeatConfig::Never,
//!                 stagger: None,
//!             }
//!         >
//!             "Hello Leptos Motion!"
//!         </MotionDiv>
//!     }
//! }
//! ```
//!
//! ## Core Concepts
//!
//! ### Animation Values
//!
//! Animation values represent different types of animatable properties:
//!
//! ```rust,no_run
//! use leptos_motion::*;
//!
//! let opacity = AnimationValue::Number(1.0);
//! let position = AnimationValue::Pixels(100.0);
//! let rotation = AnimationValue::Degrees(45.0);
//! let color = AnimationValue::Color("#ff0000".to_string());
//! ```
//!
//! ### Transitions
//!
//! Configure how animations behave:
//!
//! ```rust,no_run
//! # use leptos_motion::*;
//! // Spring animation
//! let spring = Transition {
//!     ease: Easing::Spring(SpringConfig {
//!         stiffness: 100.0,
//!         damping: 10.0,
//!         mass: 1.0,
//!         ..Default::default()
//!     }),
//!     ..Default::default()
//! };
//!
//! // Tween animation
//! let tween = Transition {
//!     duration: Some(0.3),
//!     ease: Easing::EaseInOut,
//!     delay: Some(0.1),
//!     ..Default::default()
//! };
//! ```
//!
//! ### Gestures
//!
//! Add interactivity to your animations:
//!
//! ```rust,no_run
//! # use leptos::*;
//! # use leptos_motion::*;
//! # use std::collections::HashMap;
//! # fn main() {
//! let mut hover_target = HashMap::new();
//! hover_target.insert("scale".to_string(), AnimationValue::Number(1.1));
//!
//! let mut tap_target = HashMap::new();
//! tap_target.insert("scale".to_string(), AnimationValue::Number(0.9));
//!
//! let _view = view! {
//!     <MotionDiv
//!         while_hover=hover_target
//!         while_tap=tap_target
//!         drag=DragConfig::default()
//!     >
//!         "Interactive element"
//!     </MotionDiv>
//! };
//! # }
//! ```
