}

The layout style for a DOM node.

Mirrors ink’s Styles type (styles.ts) with every prop that ink’s apply* functions write to yoga (styles.ts:415–777). Layout-inert props (text color, background, border colors) are carried as raw strings for the renderer (M1-5) without influencing the taffy layout pass.

Shorthand resolution

• overflow shorthand: resolved JS-side in Box.tsx before setStyle — only overflow_x/overflow_y per-axis values reach Rust.
• margin/marginX/marginY, padding/paddingX/paddingY, gap shorthands: NOT resolved JS-side (yoga handles via EDGE_ALL / GUTTER_ALL). Rust carries these shorthands; the taffy mapping collapses them with an Option::or cascade.

Fields

position: Option<Position>

top: Option<Dim>

right: Option<Dim>

bottom: Option<Dim>

left: Option<Dim>

margin: Option<Lp>

Shorthand — applies to all four edges (yoga EDGE_ALL).

margin_x: Option<Lp>

Horizontal shorthand — left + right (yoga EDGE_HORIZONTAL).

margin_y: Option<Lp>

Vertical shorthand — top + bottom (yoga EDGE_VERTICAL).

margin_top: Option<Lp>

margin_right: Option<Lp>

margin_bottom: Option<Lp>

margin_left: Option<Lp>

padding: Option<Lp>

Shorthand — applies to all four edges.

padding_x: Option<Lp>

Horizontal shorthand — left + right.

padding_y: Option<Lp>

Vertical shorthand — top + bottom.

padding_top: Option<Lp>

padding_right: Option<Lp>

padding_bottom: Option<Lp>

padding_left: Option<Lp>

flex_direction: Option<FlexDir>

flex_wrap: Option<FlexWrap>

flex_grow: Option<f32>

flex_shrink: Option<f32>

flex_basis: Option<Dim>

flexBasis — yoga accepts number (points), percent string, or auto.

align_items: Option<Align>

align_self: Option<Align>

None encodes auto (taffy has no explicit AlignSelf::Auto variant).

align_content: Option<ContentAlign>

justify_content: Option<ContentAlign>

width: Option<Dim>

height: Option<Dim>

min_width: Option<Dim>

min_height: Option<Dim>

max_width: Option<Dim>

max_height: Option<Dim>

aspect_ratio: Option<f32>

display: Option<Display>

border_style: Option<BorderStyle>

borderStyle value (styles.ts:255, 745). Some(_) → border active, layout width = 1 per enabled edge. None → no border (width = 0). Renderer uses the variant to select box-drawing characters (M1-5).

border_top: Option<bool>

borderTop === false disables the top border edge (styles.ts:748-749).

border_right: Option<bool>

border_bottom: Option<bool>

border_left: Option<bool>

gap: Option<f32>

All-axes shorthand (yoga GUTTER_ALL).

column_gap: Option<f32>

row_gap: Option<f32>

text_wrap: Option<TextWrap>

textWrap mode for ink-text nodes. None → default Wrap (matches ink’s ?? 'wrap' fallback at dom.ts:242).

overflow_x: Option<Overflow>

overflow_y: Option<Overflow>

background_color: Option<String>

border_color: Option<String>

border_top_color: Option<String>

border_right_color: Option<String>

border_bottom_color: Option<String>

border_left_color: Option<String>

border_background_color: Option<String>

border_top_background_color: Option<String>

border_right_background_color: Option<String>

border_bottom_background_color: Option<String>

border_left_background_color: Option<String>

border_dim_color: Option<bool>

border_top_dim_color: Option<bool>

border_right_dim_color: Option<bool>

border_bottom_dim_color: Option<bool>

border_left_dim_color: Option<bool>

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.

impl PartialEq for Style

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