Enum PixelData 

pub enum PixelData {
    U8(Vec<u8>),
    U16(Vec<u16>),
    F32(Vec<f32>),
}

A packed image buffer. All pixels share one depth, stored once for the whole buffer.

Prefer this to a Vec<PixelDepth>, which pays 8 bytes per pixel to tag each one individually.

Variants

U8(Vec<u8>)

8-bit unsigned components.

U16(Vec<u16>)

16-bit unsigned components.

F32(Vec<f32>)

32-bit floating point components.

Implementations

impl PixelData

pub fn len(&self) -> usize

Number of pixels in the buffer.

pub fn is_empty(&self) -> bool

Whether the buffer is empty.

pub fn iter(&self) -> Box<dyn Iterator<Item = PixelDepth> + '_>

Iterate the components as scalar PixelDepth values for depth-agnostic access.

Trait Implementations

impl Clone for PixelData

fn clone(&self) -> PixelData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelData

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

Formats the value using the given formatter.

impl From<Vec<f32>> for PixelData

fn from(value: Vec<f32>) -> PixelData

Converts to this type from the input type.

impl From<Vec<u8>> for PixelData

fn from(value: Vec<u8>) -> PixelData

Converts to this type from the input type.

impl From<Vec<u16>> for PixelData

fn from(value: Vec<u16>) -> PixelData

Converts to this type from the input type.

impl PartialEq for PixelData

fn eq(&self, other: &PixelData) -> 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 StructuralPartialEq for PixelData

impl TryFrom<PixelData> for Vec<u8>

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from( value: PixelData, ) -> Result<Vec<u8>, <Vec<u8> as TryFrom<PixelData>>::Error>

Performs the conversion.

impl TryFrom<PixelData> for Vec<u16>

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from( value: PixelData, ) -> Result<Vec<u16>, <Vec<u16> as TryFrom<PixelData>>::Error>

Performs the conversion.

impl TryFrom<PixelData> for Vec<f32>

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from( value: PixelData, ) -> Result<Vec<f32>, <Vec<f32> as TryFrom<PixelData>>::Error>

Performs the conversion.
