Module decode 

Decode traits, types, and configuration.

Trait hierarchy

                                 ┌→ Dec (implements Decode)
DecoderConfig → DecodeJob<'a> ──┤→ StreamDec (implements StreamingDecode)
                                 └→ AnimationFrameDec (implements AnimationFrameDecoder)

Object-safe dyn dispatch

DynDecoderConfig → DynDecodeJob → DynDecoder / DynAnimationFrameDecoder / DynStreamingDecoder

Codec implementors implement the generic traits. Dispatch callers use the Dyn* variants for codec-agnostic operation.

Structs

AnimationFrame

A composited full-canvas animation frame, borrowing the decoder’s canvas.

DecodeCapabilities

Describes what a decoder supports.

DecodeOutput

Output from a decode operation.

DecodePolicy

Decode security policy.

EmbeddedMetadata

Embedded non-color metadata from the image file.

OutputInfo

Predicted output from a decode operation.

OwnedAnimationFrame

A composited full-canvas animation frame with owned pixel data.

SourceColor

Source color description from the image file.

Traits

AnimationFrameDecoder

Full-frame composited animation decode.

Decode

Single-image decode. Returns owned pixels.

DecodeJob

Per-operation decode job.

DecodeRowSink

Receives decoded rows during streaming decode.

DecoderConfig

Reusable decoder configuration.

DynAnimationFrameDecoder

Object-safe full-frame animation decoder.

DynDecodeJob

Object-safe decode job.

DynDecoder

Object-safe one-shot decoder.

DynDecoderConfig

Object-safe decoder configuration.

DynStreamingDecoder

Object-safe streaming scanline-batch decoder.

SourceEncodingDetails

Codec-agnostic interface for source encoding properties.

StreamingDecode

Streaming scanline-batch decode.

Functions

is_format_available

Check whether a pixel format can be produced by selecting from available formats, considering lossless layout-compatible reinterpretation.

negotiate_pixel_format

Select the best output pixel format from available options.

Type Aliases

BoxedError

Boxed error type for type-erased codec operations.

SinkError

Boxed error type for sink failures.
