Struct OrientationMetadata 

#[non_exhaustive]
pub struct OrientationMetadata {
    pub exif: Option<Orientation>,
    pub maker_note: Option<Orientation>,
    pub auto_rotate: Option<bool>,
    pub resolved: Orientation,
    pub source: OrientationSource,
    pub policy: OrientationPolicy,
}

Orientation records of a file and the value resolved from them.

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.

exif: Option<Orientation>

The standard TIFF/EXIF Orientation tag; None when missing or not a valid value (1-8).

maker_note: Option<Orientation>

The vendor orientation record (MakerNote or equivalent), when present.

auto_rotate: Option<bool>

The camera’s Auto Rotate setting (Some(true) = on), when recorded.

resolved: Orientation

The orientation to apply to the image (equal to RawMetadata::orientation).

source: OrientationSource

Which record resolved comes from.

policy: OrientationPolicy

The policy that chose resolved.

Implementations

impl OrientationMetadata

pub fn resolve( exif: Option<Orientation>, maker_note: Option<Orientation>, auto_rotate: Option<bool>, policy: OrientationPolicy, ) -> Self

Combine the records of a file under policy.

pub fn from_container(orientation: Orientation) -> Self

Only the container’s standard orientation field is known (Normal is treated as “nothing recorded”).

pub fn camera_override(self, orientation: Orientation) -> Self

A fixed per-camera orientation that replaces whatever the file records.
