//!
//! A safe JPEGXL wrapper over `libjxl` library. Check out the original [library](https://github.com/libjxl/libjxl)
//! and the [bindings](https://github.com/inflation/jpegxl-rs/tree/master/jpegxl-sys).
//!
//! # Building
//!
//! If you wish to specify a custom library path, set the `DEP_JXL_LIB` environment variable.
//!
//! Building `libjxl` and statically linking can be enabled by using the `vendored` feature.
//!
//! If you don't want to depend on C++ standard library, disable the feature `threads`.
//!
//! # Usage
//!
//! Currently, `u8`, `u16`, `f16` and `f32` are supported as pixel types.
//!
//! ## Decoding
//!
//! ```
//! # use jpegxl_rs::*;
//! # use jpegxl_rs::decode::{PixelFormat, Metadata, Pixels, Data};
//! # || -> Result<(), Box<dyn std::error::Error>> {
//! # let sample = [];
//! let mut decoder = decoder_builder().build()?;
//! let (Metadata { width, height, ..}, pixels) = decoder.decode(&sample)?;
//! match pixels {
//! Pixels::Float(data) => { /* do something with Vec<f32> data */ },
//! Pixels::Uint8(data) => { /* do something with Vec<u8> data */ },
//! Pixels::Uint16(data) => { /* do something with Vec<u16> data */ },
//! Pixels::Float16(data) => { /* do something with Vec<f16> data */ },
//! }
//!
//! // Multi-threading
//! use jpegxl_rs::ThreadsRunner;
//! let runner = ThreadsRunner::default();
//! let mut decoder = decoder_builder()
//! .parallel_runner(&runner)
//! .build()?;
//!
//! // Customize pixel format
//! let mut decoder = decoder_builder()
//! .pixel_format(PixelFormat {
//! num_channels: 3,
//! endianness: Endianness::Big,
//! align: 8
//! })
//! .build()?;
//!
//! decoder.decode_with::<u8>(&sample);
//!
//! // You can change the settings after initialization
//! decoder.skip_reorientation = Some(true);
//!
//! // Reconstruct JPEG, fallback to pixels if JPEG reconstruction is not possible
//! // This operation is finished in on pass
//! let (metadata, data) = decoder.reconstruct(&sample)?;
//! match data {
//! Data::Jpeg(jpeg) => {/* do something with the JPEG data */}
//! Data::Pixels(pixels) => {/* do something with the pixels data */}
//! }
//!
//! # Ok(()) };
//! ```
//!
//! ## Encoding
//!
//! ```
//! # use jpegxl_rs::{encoder_builder, encode::EncoderResult};
//! # || -> Result<(), Box<dyn std::error::Error>> {
//! use image::io::Reader as ImageReader;
//! let sample = ImageReader::open("../samples/sample.png")?.decode()?.to_rgba16();
//! let mut encoder = encoder_builder().build()?;
//! let buffer: EncoderResult<f32> = encoder.encode(&sample, sample.width(), sample.height())?;
//! # Ok(()) };
//! ```
//!
//! Set encoder options
//!
//! ```
//! # || -> Result<(), Box<dyn std::error::Error>> {
//! # use jpegxl_rs::{*, encode::EncoderSpeed};
//! let mut encoder = encoder_builder()
//! .lossless(true)
//! .speed(EncoderSpeed::Falcon)
//! .build()?;
//! // You can change the settings after initialization
//! encoder.lossless = false;
//! encoder.quality = 3.0;
//! # Ok(()) };
//! ```
//!
//! ## [`image`](https://crates.io/crates/image) crate integration
//!
//! The integration is enabled by default. If you don't need it, disable `image` feature.
//!
//! ```
//! use jpegxl_rs::image::ToDynamic;
//! use jpegxl_rs::decoder_builder;
//! use image::DynamicImage;
//!
//! let sample = std::fs::read("../samples/sample.jxl")?;
//! let mut decoder = decoder_builder().build()?;
//! let img = decoder.decode_to_image(&sample)?;
//! let img = decoder.decode_to_image_with::<f32>(&sample)?;
//! # Ok::<(), Box<dyn std::error::Error>>(())
//! ```
