}

Stereo viewing method advertised by a DisplayID 2.x Stereo Display Interface block (0x27).

Each variant carries the method-specific parameters. Method codes that are reserved by the spec are surfaced as StereoViewingMethodV2::Reserved with the raw method byte.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FieldSequential

Method 0x00 — Field-sequential stereo. eye_on_high_half identifies which eye view is delivered during the HIGH half of the sync signal; the other eye is delivered during the LOW half. Right corresponds to payload bit 0 = 1 (spec wording “L/R polarity 1”), Left to bit 0 = 0 (“L/R polarity 0”).

Fields

eye_on_high_half: StereoEye

Eye view delivered during the HIGH half of the sync signal.

SideBySide

Method 0x01 — Side-by-side stereo. left_half indicates which eye view occupies the left half of the frame.

Fields

left_half: StereoEye

Eye view that occupies the left half of the frame.

PixelInterleaved

Method 0x02 — Pixel-interleaved stereo. The 8-byte pattern describes an 8×8 L/R pixel mask (bit set = Left, clear = Right). MSB of each byte is the leftmost pixel of that row.

Fields

pattern: [u8; 8]

8×8 bitmap; row i, bit 7 − x selects whether pixel (x, i) is Left (1) or Right (0).

DualInterface

Method 0x03 — Dual-interface stereo. Each physical interface carries a single eye view; eye identifies which eye is delivered on this interface, and mirroring describes how the image is oriented.

Fields

eye: StereoEye

Eye view delivered over this interface.

mirroring: DualInterfaceMirroring

Mirroring applied to this interface’s image.

MultiView

Method 0x04 — Multi-view stereo. view_count is the number of views and interleaving_method_code is a vendor-defined identifier for how they interleave.

Fields

view_count: u8

Number of distinct views in the multi-view configuration.

interleaving_method_code: u8

Vendor-defined identifier describing how the views interleave.

StackedFrame

Method 0x05 — Stacked-frame stereo (top/bottom). top_half indicates which eye view occupies the top half of the frame.

Fields

top_half: StereoEye

Eye view that occupies the top half of the frame.

Proprietary

Method 0xFF — Proprietary / vendor-defined.

Reserved(u8)

Method codes reserved by the DisplayID 2.x specification (0x06–0xFE).

Trait Implementations

impl Clone for StereoViewingMethodV2

fn clone(&self) -> StereoViewingMethodV2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StereoViewingMethodV2

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

Formats the value using the given formatter.

impl PartialEq for StereoViewingMethodV2

fn eq(&self, other: &StereoViewingMethodV2) -> 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.
