Enum Color 

pub enum Color {
    Hex(String),
    Rgb(u8, u8, u8),
}

A color value for QR code rendering.

Used for QrStyle::fg_color and QrStyle::bg_color.

Variants

Hex(String)

Hex string with # prefix: "#000000" (6-digit) or "#000" (3-digit shorthand).

Rgb(u8, u8, u8)

RGB components (red, green, blue), each 0–255.

Implementations

impl Color

pub fn to_hex(&self) -> Result<String, QrError>

Resolves the color to a lowercase hex string with # prefix (e.g. "#1a1a2e").

Three-digit shorthand is expanded ("#fff" becomes "#ffffff").

Returns QrError::InvalidColor if the hex value is malformed (missing #, wrong length, or non-hex characters).

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 Display for Color

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

Formats the value using the given formatter.

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.
