Struct ImageMetadata 

pub struct ImageMetadata<E: ExifRepr = Exif> {
    pub exif: Option<E>,
    pub format: Option<ImageFormatMetadata>,
}

Structured image-metadata view: EXIF (if any) plus format-specific metadata (if any).

Default E = Exif — eager EXIF representation. The MediaParser::parse_image_metadata method returns ImageMetadata<ExifIter> (lazy); convert to the default eager form via .into() when desired.

Forward-compat note: this struct is shaped to be reused unchanged by a future v4 redesign of the Metadata enum (Metadata::Image(ImageMetadata)).

Fields

exif: Option<E>

EXIF tags found in the source image, if any. For PNG, this includes legacy Raw profile type {exif,APP1} hex-encoded EXIF transparently merged.

format: Option<ImageFormatMetadata>

Format-specific metadata that does not fit the EXIF/IFD abstraction (e.g. PNG tEXt chunks).

Trait Implementations
