Enum Background

pub enum Background {
    None,
    Color(Color),
}

Widget background fill.

Possible values are no fill and a solid Background::Color.

Examples

use ailloli_ui_core::style::{Background, Color};
assert!(Background::color(Color::WHITE).is_visible());

Variants

None

No background.

Color(Color)

Solid linear-RGBA color, including potentially transparent colors.

Implementations

impl Background

pub fn color(color: Color) -> Self

Creates a solid color background.

Examples

use ailloli_ui_core::style::{Background, Color};
assert_eq!(Background::color(Color::BLACK), Background::Color(Color::BLACK));

pub fn is_visible(self) -> bool

Returns true when the variant carries a color.

This reports configuration presence, not effective opacity: a fully transparent Color still returns true.

Examples

use ailloli_ui_core::style::{Background, Color};
assert!(Background::color(Color::TRANSPARENT).is_visible());
assert!(!Background::None.is_visible());

Trait Implementations

impl Clone for Background

fn clone(&self) -> Background

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Background

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

Formats the value using the given formatter.

impl Default for Background

fn default() -> Background

Returns the “default value” for a type.

impl PartialEq for Background

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

impl Copy for Background

impl StructuralPartialEq for Background
