Struct ColorCode

pub struct ColorCode(/* private fields */);

Packed VGA attribute byte for text mode: bits 0–3 = foreground color; 4–6 = background color; 7 = blink/bright (mode-dependent).

Implementations

impl ColorCode

pub const fn new(fg: Color, bg: Color, blink: bool) -> Self

Build a color code from fg/bg/blink. Note: with Attribute Controller mode bit 7 = blink enabled, bit 7 here blinks. If blink is disabled in the controller, bit 7 acts as “bright background”.

pub const fn as_u8(self) -> u8

Raw byte as written to the high byte of the cell.

pub const fn from_u8(b: u8) -> Self

Construct directly from a packed byte (for interop/tests).

pub const fn fg(self) -> Color

Extractors (handy for debugging/tools)

pub const fn bg(self) -> Color

Note: background uses only 3 bits (0..=7). Bright backgrounds require disabling blink in the Attribute Controller and repurposing bit 7.

pub const fn blink(self) -> bool

Trait Implementations

impl Clone for ColorCode

fn clone(&self) -> ColorCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColorCode

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

Formats the value using the given formatter.

impl PartialEq for ColorCode

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