Struct SolidColor 

pub struct SolidColor { /* private fields */ }

RGBA color with components in the 0.0–1.0 range.

Implementations

impl SolidColor

pub fn r(&self) -> f64

Red component (0.0–1.0).

pub fn g(&self) -> f64

Green component (0.0–1.0).

pub fn b(&self) -> f64

Blue component (0.0–1.0).

pub fn a(&self) -> f64

Alpha component (0.0–1.0).

pub fn rgba(&self) -> (f64, f64, f64, f64)

All four components as a tuple (r, g, b, a), each 0.0–1.0.

impl SolidColor

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

Create from 0–255 RGB values with full opacity.

pub fn to_rgb(&self) -> (u8, u8, u8)

Convert to 0–255 RGB tuple.

pub fn from_hex(hex: &str) -> Option<Self>

Parse a hex string (with or without #, 3, 6, or 8 chars).

8-char hex is interpreted as RRGGBBAA. 3 and 6-char hex default to full opacity.

fn main() {
    let color = RwSignal::new(SolidColor::from_hex("FFFFFF").unwrap());

    floem::Application::new()
        .window(
            move |_| {
                solid_picker(color).on_event_stop(floem::event::EventListener::WindowClosed, |_| {
                    floem::quit_app()
                })
            },
            Some(
                WindowConfig::default()
                    .size((232.0, 460.0))
                    .title("floem-picker"),
            ),
        )
        .run();
}

pub fn to_hex(&self) -> String

Format as uppercase hex (no # prefix).

Returns 6 chars (RRGGBB) when alpha is 1.0. Returns 8 chars (RRGGBBAA) when alpha is less than 1.0.

pub fn from_hsb(h: f64, s: f64, b: f64, a: f64) -> Self

Create from HSB/HSV values (all 0.0–1.0).

pub fn to_hsb(&self) -> (f64, f64, f64)

Convert to HSB (all 0.0–1.0). Returns (h, s, b).

pub fn from_hsl(h: f64, s: f64, l: f64, a: f64) -> Self

Create from HSL values (all 0.0–1.0).

pub fn to_hsl(&self) -> (f64, f64, f64)

Convert to HSL (all 0.0–1.0). Returns (h, s, l).

pub fn from_rgba(r: f64, g: f64, b: f64, a: f64) -> Self

Create from f64 RGBA. Values are clamped to 0.0–1.0.

Trait Implementations

impl Clone for SolidColor

fn clone(&self) -> SolidColor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SolidColor

impl Debug for SolidColor

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

Formats the value using the given formatter.

impl Default for SolidColor

fn default() -> Self

Returns the “default value” for a type.

impl Display for SolidColor

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

Formats as #RRGGBB or #RRGGBBAA (when alpha < 1.0).

impl FromStr for SolidColor

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a hex color string (with or without #, 3/6/8 hex chars).

type Err = String

The associated error which can be returned from parsing.

impl PartialEq for SolidColor

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