Struct Color 

pub struct Color {
    pub red: u8,
    pub green: u8,
    pub blue: u8,
    pub alpha: f32,
}

Represents an RGB color.

Fields

red: u8

Red component (0-255)

green: u8

Green component (0-255)

blue: u8

Blue component (0-255)

alpha: f32

Alpha component (0-1)

Implementations

impl Color

pub fn new(red: u8, green: u8, blue: u8) -> Self

Creates a new Color instance.

Arguments

• red - The red component (0-255)
• green - The green component (0-255)
• blue - The blue component (0-255)

Returns

A new Color instance.

pub fn with_alpha(red: u8, green: u8, blue: u8, alpha: f32) -> Self

Creates a new Color instance with an alpha component. The alpha component is a floating-point value between 0.0 and 1.0. A value of 0.0 represents full transparency, while 1.0 is fully opaque. Values between 0.0 and 1.0 represent varying levels of transparency.

Arguments

• red - The red component (0-255)
• green - The green component (0-255)
• blue - The blue component (0-255)
• alpha - The alpha component (0.0-1.0)

Returns

A new Color instance.

pub fn interpolate(&self, color: &Color, percentage: f32) -> Self

Interpolates between two RGB colors based on percentage.

Arguments

• color - The target color to interpolate towards
• percentage - The interpolation percentage (0.0 to 100.0)

Returns

A new Color instance representing the interpolated color.

pub fn from_hex(hex: &str) -> Result<Self, ColorError>

Tries to create a Color from a hexadecimal color string.

Arguments

• hex - A string slice that holds the hexadecimal color code (e.g., “#FF00FF”)

Returns

A Result containing either the created Color or a ColorError.

pub fn from_rgba(input: &str) -> Result<Self, ColorError>

Tries to create a Color from a rgba color string. The format is “rgba(r, g, b, a)” where r, g, b are the red, green, blue components (0-255) Or “rgb(r, g, b)” where r, g, b are the red, green, blue components (0-255) and a is the alpha component (0.0-1.0). The spaces are optional. The alpha component is optional and defaults to 1.0.

Arguments

• input - A string slice that holds the rgba color code (e.g., “rgba(255, 128, 64, 0.5)”, “rgb(255, 128, 64)”)

Returns

A Result containing either the created Color or a ColorError.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

impl TryFrom<&str> for Color

fn try_from(value: &str) -> Result<Self, Self::Error>

Tries to create a Color from various string formats.

Arguments

• value - A string slice that holds the color code (e.g., “#FF8040”, “#FF8040FF”, “rgba(255, 128, 64, 0.5)”)

Returns

A Result containing either the created Color or a ColorError.

type Error = ColorError

The type returned in the event of a conversion error.
