Struct epaint::Hsva

pub struct Hsva {
    pub h: f32,
    pub s: f32,
    pub v: f32,
    pub a: f32,
}

Hue, saturation, value, alpha. All in the range [0, 1]. No premultiplied alpha.

Fields

h: f32

hue 0-1

s: f32

saturation 0-1

v: f32

value 0-1

a: f32

alpha 0-1. A negative value signifies an additive color (and alpha is ignored).

Trait Implementations

impl Clone for Hsva

fn clone(&self) -> Hsva

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Hsva

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

Formats the value using the given formatter.

impl Default for Hsva

fn default() -> Hsva

Returns the “default value” for a type.

impl From<Color32> for Hsva

fn from(srgba: Color32) -> Hsva

Converts to this type from the input type.

impl From<Hsva> for Color32

fn from(hsva: Hsva) -> Color32

Converts to this type from the input type.

impl From<Hsva> for HsvaGamma

fn from(hsva: Hsva) -> HsvaGamma

Converts to this type from the input type.

impl From<Hsva> for Rgba

fn from(hsva: Hsva) -> Rgba

Converts to this type from the input type.

impl From<HsvaGamma> for Hsva

impl PartialEq for Hsva

fn eq(&self, other: &Hsva) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
