#![doc = include_str!("../README.md")]
//!
//! ---
//!
//! # API Documentation
//!
//! Safe, **zero-runtime-dependency** Rust bindings for Apple's
//! [VideoToolbox](https://developer.apple.com/documentation/videotoolbox)
//! framework — hardware-accelerated H.264, HEVC, and ProRes codecs on macOS.
//!
//! Unlike the rest of the doom-fish suite, `VideoToolbox` is a pure C framework,
//! so this crate does **not** ship a Swift bridge — all bindings are direct
//! `extern "C"` declarations against the system framework.
//!
//! # Quick start
//!
//! ```rust,no_run
//! use videotoolbox::prelude::*;
//! use apple_cf::iosurface::IOSurface;
//!
//! # fn main() -> Result<(), Box<dyn std::error::Error>> {
//! let surface = IOSurface::create(1920, 1080, u32::from_be_bytes(*b"BGRA"), 4)
//!     .ok_or("failed to allocate IOSurface")?;
//!
//! let encoder = CompressionSession::builder(1920, 1080, Codec::H264)
//!     .with_real_time(true)
//!     .with_average_bit_rate(8_000_000)
//!     .with_expected_frame_rate(60.0)
//!     .build()?;
//!
//! let encoded = encoder.encode(&surface, (0, 60))?;
//! println!("Got {} bytes of H.264", encoded.data.len());
//! # Ok(())
//! # }
//! ```
