Struct CanvasColor 

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

A 3-bit canvas-level color index used for pixel compositing.

Values range from 0 (NORMAL) to 7 (WHITE). Colors compose additively via BitOr: for example, BLUE | RED yields MAGENTA.

Implementations

impl CanvasColor

pub const NORMAL: Self

No color (default foreground).

pub const BLUE: Self

Blue (bit 0).

pub const RED: Self

Red (bit 1).

pub const MAGENTA: Self

Magenta (blue | red).

pub const GREEN: Self

Green (bit 2).

pub const CYAN: Self

Cyan (blue | green).

pub const YELLOW: Self

Yellow (red | green).

pub const WHITE: Self

White (all bits set).

pub const fn new(value: u8) -> Option<Self>

Creates a canvas color from a raw index. Returns None if value > 7.

pub const fn as_u8(self) -> u8

Returns the underlying u8 index.

Trait Implementations

impl BitOr for CanvasColor

type Output = CanvasColor

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl Clone for CanvasColor

fn clone(&self) -> CanvasColor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CanvasColor

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

Formats the value using the given formatter.

impl Default for CanvasColor

fn default() -> Self

Returns the “default value” for a type.

impl Hash for CanvasColor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CanvasColor

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