Module api 

Three-layer public API: Config → Request → Encoder.

use jxl_encoder::{LosslessConfig, LossyConfig, PixelLayout};

// Simple — one line, no request visible
let jxl = LossyConfig::new(1.0)
    .encode(&pixels, 800, 600, PixelLayout::Rgb8)?;

// Full control — request layer for metadata, limits, cancellation
let jxl = LosslessConfig::new()
    .encode_request(800, 600, PixelLayout::Rgb8)
    .encode(&pixels)?;

Macros

at

Start tracing an error with crate metadata for repository links.

Structs

AnimationFrame

A single frame in an animation sequence.

AnimationParams

Animation timing parameters.

At

An error with location tracking - wraps any error type.

EncodeRequest

An encoding request — binds config + image dimensions + pixel layout.

EncodeResult

Result of an encode operation. Holds encoded data and metrics.

EncodeStats

Encode metrics collected during encoding.

ImageMetadata

Image metadata (ICC, EXIF, XMP) to embed in the JXL file.

Limits

Resource limits for encoding.

LosslessConfig

Lossless (modular) encoding configuration.

LossyConfig

Lossy (VarDCT) encoding configuration.

Unstoppable

A Stop implementation that never stops (no cooperative cancellation).

Enums

EncodeError

Encode error type.

EncodeMode

Encoding mode.

PixelLayout

Describes the pixel format of input data.

Quality

Quality specification for lossy encoding.

Traits

ResultAtExt

Extension trait for adding location tracking to Result<T, At<E>>.

Stop

Cooperative cancellation check.

Functions

at

Wrap any value in At<E> and capture the caller’s location.

Type Aliases

Result

Result type for encoding operations.
