Struct Rg8U 

pub struct Rg8U(/* private fields */);

A two-channel 8-bit unsigned color (red, green).

Implementations

impl Rg8U

pub const WHITE: Rg8U

Full white (all channels maximum).

pub const BLACK: Rg8U

Full black (all channels zero).

pub const fn new(r: u8, g: u8) -> Self

Creates a new two-channel color from u8 red and green values.

pub const fn bytes(&self) -> [u8; 2]

Return color from raw bytes.

pub const fn from_bytes(bytes: [u8; 2]) -> Self

Return color from raw bytes.

pub const fn bits(&self) -> u16

Returns the raw u16 bit pattern (little-endian).

pub const fn from_bits(bits: u16) -> Self

Constructs from a raw u16 bit pattern (little-endian).

pub const fn bits_interleaved(&self) -> u16

Returns the channels as an interleaved u16 bit pattern.

pub const fn from_bits_interleaved(bits: u16) -> Self

Constructs from an interleaved u16 bit pattern.

pub const fn r(&self) -> u8

Returns the red channel value.

pub const fn g(&self) -> u8

Returns the green channel value.

pub const fn into_f32(self) -> Rg32F

Converts this color to its 32-bit float representation.

pub const fn from_f32(rg: Rg32F) -> Rg8U

Converts from a 32-bit float representation, clamping each channel to [0, 255].

pub fn wrapping_add(self, other: Self) -> Self

Wrapping unsigned addition per channel.

pub fn wrapping_sub(self, other: Self) -> Self

Wrapping unsigned subtraction per channel.

pub const fn diff(a: Self, b: Self) -> Vec2

Returns the per-channel difference as a Vec2.

pub const fn distance_squared(a: Self, b: Self) -> f32

Returns the squared Euclidean distance.

pub fn distance(a: Self, b: Self) -> f32

Returns the Euclidean distance.

Trait Implementations

impl Clone for Rg8U

fn clone(&self) -> Rg8U

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rg8U

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

Formats the value using the given formatter.

impl FixedCode for Rg8U

const SIZE: usize

type Array = [u8; 2]

type Error = Infallible

fn fix_encode(&self) -> Self::Array

fn fix_decode(input: &Self::Array) -> Result<Self, Self::Error>

fn fix_write(&self, write: &mut impl Write) -> Result<()>

Encodes self and writes the resulting bytes to write.

fn fix_read(read: &mut impl Read) -> Result<Self>

Reads exactly SIZE bytes from read and decodes them.

impl Hash for Rg8U

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 Rg8U

fn eq(&self, other: &Rg8U) -> 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.
