Pixel format identifier.

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.

Rgb = 1

Packed RGB [H, W, 3]

Rgba = 2

Packed RGBA [H, W, 4]

Bgra = 3

Packed BGRA [H, W, 4]

Grey = 4

Grayscale [H, W, 1]

Yuyv = 5

Packed YUV 4:2:2, YUYV byte order [H, W, 2]

Vyuy = 6

Packed YUV 4:2:2, VYUY byte order [H, W, 2]

Nv12 = 7

Semi-planar YUV 4:2:0 [H*3/2, W] or multiplane [H, W] + [H/2, W]

Nv16 = 8

Semi-planar YUV 4:2:2 [H*2, W] or multiplane [H, W] + [H, W]

PlanarRgb = 9

Planar RGB, channels-first [3, H, W]

PlanarRgba = 10

Planar RGBA, channels-first [4, H, W]

Implementations

impl PixelFormat

pub const fn channels(&self) -> usize

Returns the number of channels for this pixel format.

For semi-planar formats (NV12, NV16), this returns 1 (the luma channel count for the primary plane). For packed formats, this is the total number of interleaved components per pixel.

pub const fn layout(&self) -> PixelLayout

Returns the memory layout category for this pixel format.

pub const fn is_yuv(&self) -> bool

Returns true if this format encodes YUV (luma/chroma) data.

pub const fn has_alpha(&self) -> bool

Returns true if this format includes an alpha channel.

pub const fn to_fourcc(&self) -> u32

Returns the V4L2/DRM FourCC code for this format, or 0 for formats that have no standard FourCC representation (e.g., PlanarRgb).

pub const fn from_fourcc(fourcc: u32) -> Option<Self>

Converts a V4L2/DRM FourCC code to a PixelFormat, returning None for unrecognized or zero codes.

Trait Implementations

impl Clone for PixelFormat

fn clone(&self) -> PixelFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PixelFormat

impl Debug for PixelFormat

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PixelFormat

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PixelFormat

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

Formats the value using the given formatter.

impl Eq for PixelFormat

impl Hash for PixelFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PixelFormat

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

impl Serialize for PixelFormat

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
