Struct ImageMetadata 

pub struct ImageMetadata {

    pub camera: CameraInfo,
    pub exif: ExifInfo,
    pub datetime: DateTimeInfo,
    pub gps: GpsInfo,
    pub dng_color: DngColorInfo,
    pub dng_calibration: DngCalibrationInfo,
    pub dng_profile: DngProfileInfo,
    pub image: ImageInfo,
    pub xmp: Option<Vec<u8>>,
    pub icc_profile: Option<Vec<u8>>,
    pub exif_raw: Option<Vec<u8>>,
    pub makernote_raw: Option<Vec<u8>>,
    pub iptc_raw: Option<Vec<u8>>,
    pub extra: Vec<MetadataEntry>,
}

Complete image metadata — unified superset of all supported formats.

This struct is designed for extension. Common metadata has dedicated typed fields (camera, exif, …); anything the library does not model is preserved losslessly via the raw-blob fields (exif_raw, xmp, …) and the typed generic table extra, so new formats never force a schema change.

Fields

camera: CameraInfo

Camera identification

exif: ExifInfo

EXIF exposure settings

datetime: DateTimeInfo

Date/time information

gps: GpsInfo

GPS location data

dng_color: DngColorInfo

DNG color science

dng_calibration: DngCalibrationInfo

DNG calibration/noise

dng_profile: DngProfileInfo

DNG profile data

image: ImageInfo

Image-level metadata

xmp: Option<Vec<u8>>

Raw XMP (XML) metadata bytes, if present in source image

icc_profile: Option<Vec<u8>>

Raw embedded ICC color profile bytes, if present

exif_raw: Option<Vec<u8>>

Full raw EXIF block (TIFF byte stream) exactly as embedded, if present

makernote_raw: Option<Vec<u8>>

Raw manufacturer MakerNote blob, uninterpreted, if present

iptc_raw: Option<Vec<u8>>

Raw IPTC IIM block, if present

extra: Vec<MetadataEntry>

Typed generic tag table.

Holds metadata tags as a complete typed mirror of the source — including tags also surfaced as dedicated fields above, and anything the library does not model. Guarantees no metadata is silently dropped.

Stored as a Vec (not a map) so it serializes cleanly in every serde format and preserves source ordering. Use get / insert for map-like access.

Implementations

impl ImageMetadata

pub fn get( &self, namespace: MetadataNamespace, tag: &str, ) -> Option<&MetadataValue>

Look up a generic tag in extra.

Returns the first entry matching namespace and tag.

pub fn insert(&mut self, key: MetadataKey, value: MetadataValue)

Insert or overwrite a generic tag in extra.

If an entry with the same key already exists, its value is replaced; otherwise the entry is appended.

Trait Implementations

impl Clone for ImageMetadata

fn clone(&self) -> ImageMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ImageMetadata

fn default() -> ImageMetadata

Returns the “default value” for a type.

impl PartialEq for ImageMetadata

fn eq(&self, other: &ImageMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
