Enum BackgroundPattern 

pub enum BackgroundPattern {
    None,
    Solid,
    Dots,
    Lines,
    DiagonalForward,
    CrossStitch,
}

A fill pattern for the background of a regular top-level window.

Patterns are 1-bit and snapped to a small physical-pixel grid so they stay crisp at any DPI — retro desktop texture, not anti-aliased wallpaper. The foreground (the dots / lines) is drawn in one of the named PATTERN_COLORS; the gaps stay the window’s base background color.

Variants

None

Plain background — no texture.

Solid

Flood the whole window with the pattern color.

Dots

A staggered field of dots (every other row offset half a step), like the classic Mac desktop.

Lines

Horizontal hairlines every 4px.

DiagonalForward

Forward diagonal hatching (///).

CrossStitch

Two crossing diagonals — a cross-stitch / XXXX weave.

Implementations

impl BackgroundPattern

pub const ALL: [BackgroundPattern; 6]

Every pattern, in the order the patterns demo rotates through them.

pub fn name(self) -> &'static str

Canonical lower-case name — both the display label and the token accepted by SAUDADE_WINDOW_PATTERN.

pub fn from_name(s: &str) -> Option<Self>

Parse a name token (case-insensitive, _ treated as -). Returns None for anything unrecognized.

pub fn next(self) -> Self

The next pattern in BackgroundPattern::ALL, wrapping at the end.

Trait Implementations

impl Clone for BackgroundPattern

fn clone(&self) -> BackgroundPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackgroundPattern

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

Formats the value using the given formatter.

impl PartialEq for BackgroundPattern

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