Struct Style 

pub struct Style {
    pub layout: LayoutStyle,
    pub spacing: SpacingStyle,
    pub sizing: SizingStyle,
    pub visual: VisualStyle,
}

Style properties for a widget

Contains all CSS-like properties that can be applied to a widget. Properties are organized into logical groups:

• layout: Display mode, flexbox, and grid properties
• spacing: Padding, margin, and position offsets
• sizing: Width, height, and min/max constraints
• visual: Colors, border, opacity, and visibility

For backward compatibility, individual properties can still be accessed directly (e.g., style.display instead of style.layout.display).

Fields

layout: LayoutStyle

Layout properties (display, flex, grid)

spacing: SpacingStyle

Spacing properties (padding, margin, offsets)

sizing: SizingStyle

Sizing properties (width, height, min/max)

visual: VisualStyle

Visual properties (colors, border, opacity)

Implementations

impl Style

pub fn display(&self) -> Display

Display mode (flex, block, grid, none) - non-inherited

pub fn position(&self) -> Position

Position mode (static, relative, absolute, fixed) - non-inherited

pub fn flex_direction(&self) -> FlexDirection

Flex direction (row, column) - non-inherited

pub fn justify_content(&self) -> JustifyContent

Main axis alignment - non-inherited

pub fn align_items(&self) -> AlignItems

Cross axis alignment - non-inherited

pub fn gap(&self) -> u16

Gap between flex/grid items - non-inherited

pub fn column_gap(&self) -> Option<u16>

Column gap for grid - non-inherited

pub fn row_gap(&self) -> Option<u16>

Row gap for grid - non-inherited

pub fn grid_template_columns(&self) -> &GridTemplate

Grid template columns - non-inherited

pub fn grid_template_rows(&self) -> &GridTemplate

Grid template rows - non-inherited

pub fn grid_column(&self) -> GridPlacement

Grid column placement - non-inherited

pub fn grid_row(&self) -> GridPlacement

Grid row placement - non-inherited

pub fn padding(&self) -> Spacing

Inner padding - non-inherited

pub fn margin(&self) -> Spacing

Outer margin - non-inherited

pub fn top(&self) -> Option<i16>

Top offset - non-inherited

pub fn right(&self) -> Option<i16>

Right offset - non-inherited

pub fn bottom(&self) -> Option<i16>

Bottom offset - non-inherited

pub fn left(&self) -> Option<i16>

Left offset - non-inherited

pub fn width(&self) -> Size

Width constraint - non-inherited

pub fn height(&self) -> Size

Height constraint - non-inherited

pub fn min_width(&self) -> Size

Minimum width - non-inherited

pub fn max_width(&self) -> Size

Maximum width - non-inherited

pub fn min_height(&self) -> Size

Minimum height - non-inherited

pub fn max_height(&self) -> Size

Maximum height - non-inherited

pub fn border_style(&self) -> BorderStyle

Border style - non-inherited

pub fn border_color(&self) -> Color

Border color - non-inherited

pub fn color(&self) -> Color

Text/foreground color - INHERITED

pub fn background(&self) -> Color

Background color - non-inherited

pub fn opacity(&self) -> f32

Opacity (0.0 to 1.0) - INHERITED

pub fn visible(&self) -> bool

Visibility flag - INHERITED

pub fn z_index(&self) -> i16

Z-index for stacking order - non-inherited

impl Style

pub fn inherit(parent: &Style) -> Self

Inherit inheritable properties from parent style

CSS Inherited Properties:

• color - text color
• opacity - visual opacity
• visible - visibility

Non-inherited properties are reset to their defaults.

pub fn with_inheritance(&self, parent: &Style) -> Self

Inherit from parent, then apply own rules

This is the main method for computing inherited styles:

1. Start with inherited values from parent
2. Apply this style’s explicitly set values

Trait Implementations

impl Clone for Style

fn clone(&self) -> Style

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Style

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

Formats the value using the given formatter.

impl Default for Style

fn default() -> Style

Returns the “default value” for a type.
