//! Unified record! macro for animation recording
//!
//! This module provides the `record!` macro which unifies all animation
//! recording patterns into a single, ergonomic API.
//!
//! # Patterns
//!
//! ```rust,ignore
//! use ruviz::record;
//!
//! // Frame count
//! record!("out.gif", 60, |t| Plot::new().line(&x, &y))?;
//!
//! // Duration in seconds
//! record!("out.gif", 2 secs, |t| Plot::new().scatter(&x, &y))?;
//!
//! // Duration in milliseconds
//! record!("out.gif", 500 ms, |t| Plot::new().bar(&x, &y))?;
//!
//! // Custom framerate
//! record!("out.gif", 2 secs @ 60 fps, |t| Plot::new().line(&x, &y))?;
//!
//! // With configuration
//! let config = RecordConfig::new().dimensions(1920, 1080);
//! record!("out.gif", 60, config: config, |t| Plot::new().line(&x, &y))?;
//!
//! // Reactive plot (no closure needed)
//! record!("out.gif", &reactive_plot, 2 secs)?;
//! record!("out.gif", &reactive_plot, 2 secs @ 30 fps)?;
//! ```

/// Unified macro for animation recording.
///
/// This macro provides a single entry point for all animation recording patterns,
/// replacing the multiple `record_*` functions with a cleaner, more consistent API.
///
/// # Patterns
///
/// ## Closure-based (Plot created per frame)
///
/// ```rust,ignore
/// // Frame count (60 frames at default 30fps)
/// record!("out.gif", 60, |t| Plot::new().line(&x, &y))?;
///
/// // Duration in seconds (default 30fps)
/// record!("out.gif", 2 secs, |t| Plot::new().scatter(&x, &y))?;
///
/// // Duration in milliseconds
/// record!("out.gif", 500 ms, |t| Plot::new().bar(&x, &y))?;
///
/// // Custom framerate
/// record!("out.gif", 2 secs @ 60 fps, |t| Plot::new().line(&x, &y))?;
///
/// // With configuration
/// let config = RecordConfig::new().dimensions(1920, 1080);
/// record!("out.gif", 60, config: config, |t| Plot::new().line(&x, &y))?;
/// ```
///
/// ## Reactive (Plot created once)
///
/// ```rust,ignore
/// let y_signal = signal::of(|t| compute_y(t));
/// let plot = Plot::new().line(&x, y_signal);
///
/// // Reactive with duration
/// record!("out.gif", &plot, 2 secs)?;
///
/// // Reactive with custom fps
/// record!("out.gif", &plot, 2 secs @ 30 fps)?;
///
/// // Reactive with config
/// let config = RecordConfig::new().dimensions(1920, 1080);
/// record!("out.gif", &plot, 2 secs, config: config)?;
/// ```
