Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

make: String

Make as written in the file.

model: String

Model as written in the file.

canonical_make: String

Normalised maker name (“Canon”, “Nikon”, “Sony”, …).

canonical_model: String

Normalised model name (aliases resolved).

unique_camera_model: Option<String>

DNG UniqueCameraModel or equivalent.

software: Option<String>

Writing software (EXIF Software tag).

firmware: Option<String>

Camera firmware version, from maker notes where available.

serial: Option<String>

Camera body serial number.

artist: Option<String>

Artist / author.

copyright: Option<String>

Copyright notice.

lens: LensInfo

Lens information (fields are None when not recorded).

exposure: ExposureInfo

Exposure parameters (fields are None when not recorded).

capture_time: Option<String>

Capture timestamp, YYYY-MM-DDTHH:MM:SS[.sss][±HH:MM] when available.

gps: Option<GpsInfo>

GPS position; None unless a latitude or longitude is recorded.

orientation: Orientation

Image orientation (the resolved value of RawMetadata::orientation_info).

orientation_info: OrientationMetadata

The orientation records found in the file (standard tag and vendor record) and how the resolved RawMetadata::orientation was chosen.

format: Option<RawFormat>

Container format, when identified.

compression: Option<Compression>

Payload compression of the main RAW image, when identified.

bits_per_sample: u8

Bits per sample of the encoded data.

raw_width: u32

Full sensor buffer width (including masked borders).

raw_height: u32

Full sensor buffer height (including masked borders).

width: u32

Width after the default crop.

height: u32

Height after the default crop.

dng_version: Option<[u8; 4]>

DNG version bytes (e.g. [1, 4, 0, 0]); None for non-DNG files.

extra: Vec<(String, String)>

Free-form, vendor-specific values worth exposing (mode names, quality, crop mode…).

previews: Vec<PreviewInfo>

Embedded previews and thumbnails.

dng: Option<DngExtras>

DNG rendering hints (None for non-DNG files).

Implementations

impl RawMetadata

pub fn image_size(&self) -> Option<(u32, u32)>

The camera’s own image size recorded by the file (EXTRA_IMAGE_SIZE).

pub fn set_image_size(&mut self, width: u32, height: u32)

Record the camera’s own image size (EXTRA_IMAGE_SIZE); zero sizes are ignored.

pub fn new(make: impl Into<String>, model: impl Into<String>) -> RawMetadata

Metadata with the given make and model as written in the file; everything else empty.

pub fn set_extra(&mut self, key: &str, value: impl ToString)

Set an entry of RawMetadata::extra, replacing any existing value for key.

pub fn extra(&self, key: &str) -> Option<&str>

Look up an entry of RawMetadata::extra by key.

pub fn camera(&self) -> String

Human-friendly “Make Model” string using canonical names when known.

pub fn largest_preview(&self) -> Option<&PreviewInfo>

Largest preview.

pub fn smallest_preview(&self) -> Option<&PreviewInfo>

Smallest preview (thumbnail).
