//!
//! A safe JPEGXL wrapper over `jpeg-xl` library. Check out the original [library](https://gitlab.com/wg1/jpeg-xl)
//! and the [bindings](https://github.com/inflation/jpegxl-sys).
//!
//! # Building
//!
//! The library build `jpeg-xl` and link to `lib(std)c++` by default. Optionally, you can use `system-jxl` feature to
//! dynamically link to it. If you don't have it in the default include and library paths,
//! set them with `DEP_JXL_INCLUDE` and `DEP_JXL_LIB` respectively.
//!
//! If you don't want to depend on C++ standard library, disable `threads` feature.
//!
//! # Usage
//!
//! Currently, `u8`, `u16` and `f32`(partial) are supported as pixel types. `u32` is in the header but not implemented.
//!
//! Note: `f32` with alpha channel is not supported in encoder.
//!
//! ## Decoding
//!
//! ```
//! # use jpegxl_rs::*;
//! # || -> Result<(), Box<dyn std::error::Error>> {
//! # let sample = [];
//! let mut decoder = decoder_builder().build()?;
//!
//! // 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()
//!                       .num_channels(3)
//!                       .endianness(Endianness::Big)
//!                       .align(8)
//!                       .build()?;
//!
//! decoder.decode_to::<u8>(&sample);
//!
//! // You can change the settings after initialization
//! decoder.num_channels = 1;
//! decoder.endianness = Endianness::Native;
//! # 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("test/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-support` feature.
//!
//! ```
//! # || -> Result<(), Box<dyn std::error::Error>> {
//! use jpegxl_rs::image::ToDynamic;
//! use jpegxl_rs::decoder_builder;
//! use image::DynamicImage;
//!
//! let sample = std::fs::read("test/sample.jxl")?;
//! let decoder = decoder_builder().build()?;
//! let img = decoder.decode(&sample)?.into_dynamic_image();       
//! # Ok(()) };
//! ```
