Struct Color 

#[repr(C)]
pub struct Color {
    pub r: f32,
    pub g: f32,
    pub b: f32,
    pub a: f32,
}

RGBA color with 32-bit floating point components

Fields

r: f32

g: f32

b: f32

a: f32

Implementations

impl Color

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

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

pub fn from_rgba_bytes(r: u8, g: u8, b: u8, a: u8) -> Self

pub fn from_rgb_bytes(r: u8, g: u8, b: u8) -> Self

pub fn from_imgui_u32(abgr: u32) -> Self

Construct from an ImGui-packed color (ImU32 ABGR order).

ImGui packs colors with IM_COL32(R,G,B,A) into (A<<24)|(B<<16)|(G<<8)|R. This converts that ABGR-packed u32 into an RGBA float Color.

pub fn from_rgb_u32(rgb: u32) -> Self

Construct from an opaque 24-bit RGB value (0xRRGGBB).

pub fn to_imgui_u32(self) -> u32

Pack to ImGui ImU32 ABGR order (A<<24)|(B<<16)|(G<<8)|R.

pub fn to_array(self) -> [f32; 4]

pub fn from_array(arr: [f32; 4]) -> Self

pub fn with_alpha(self, alpha: f32) -> Self

pub fn lerp(self, other: Self, t: f32) -> Self

pub fn to_hsv(self) -> (f32, f32, f32)

pub fn from_hsv(h: f32, s: f32, v: f32) -> Self

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Color

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

Formats the value using the given formatter.

impl Default for Color

fn default() -> Self

Returns the “default value” for a type.

impl Display for Color

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

Formats the value using the given formatter.

impl From<[f32; 4]> for Color

fn from(arr: [f32; 4]) -> Self

Converts to this type from the input type.

impl From<(f32, f32, f32, f32)> for Color

fn from((r, g, b, a): (f32, f32, f32, f32)) -> Self

Converts to this type from the input type.

impl From<Color> for [f32; 4]

fn from(color: Color) -> Self

Converts to this type from the input type.

impl From<Color> for (f32, f32, f32, f32)

fn from(color: Color) -> Self

Converts to this type from the input type.

impl PartialEq for Color

fn eq(&self, other: &Color) -> 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 Copy for Color

impl StructuralPartialEq for Color
