Struct Rg32F 

pub struct Rg32F(/* private fields */);

A two-channel (red, green) color represented as 2 f32s.

Implementations

impl Rg32F

pub const WHITE: Rg32F

Full white (all channels maximum).

pub const BLACK: Rg32F

Full black (all channels zero).

pub const fn new(r: f32, g: f32) -> Self

Creates a new two-channel color from f32 red and green values.

pub const fn r(&self) -> f32

Returns the red channel value.

pub const fn g(&self) -> f32

Returns the green channel value.

pub const fn with_b(self, b: f32) -> Rgb32F

Extends to a three-channel color by appending a blue component.

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

Linearly interpolates between two colors component-wise.

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.

pub const fn offset(self, offset: Vec2) -> Self

Translates this color by the given offset.

Trait Implementations

impl Clone for Rg32F

fn clone(&self) -> Rg32F

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rg32F

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

Formats the value using the given formatter.

impl FixedCode for Rg32F

const SIZE: usize

type Array = [u8; 8]

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 PartialEq for Rg32F

fn eq(&self, other: &Rg32F) -> 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.
