Struct LayoutStyle

pub struct LayoutStyle {
    pub padding_top: i32,
    pub padding_bottom: i32,
    pub padding_left: i32,
    pub padding_right: i32,
    pub margin_top: i32,
    pub margin_bottom: i32,
    pub margin_left: i32,
    pub margin_right: i32,
    pub gap_row: i32,
    pub gap_col: i32,
}

Expand description

Fully resolved layout-related style properties (padding, margin, gap).

Produced by resolve_layout_style from the style cascade. The run_layout pass reads this struct for each node before computing geometry.

Mirrors the LPAR-08 TextStyle pattern: a new resolved struct alongside StylePatch additions; the frozen 5-field core::style::Style is not extended.

§Defaults

All fields resolve to 0 when no style entry provides a value (matching LPAR-07 §7.4 reserved defaults for padding and margin).

Fields§

§padding_top: i32

Padding on the top edge in pixels.

§padding_bottom: i32

Padding on the bottom edge in pixels.

§padding_left: i32

Padding on the left edge in pixels.

§padding_right: i32

Padding on the right edge in pixels.

§margin_top: i32

Margin on the top edge in pixels.

§margin_bottom: i32

Margin on the bottom edge in pixels.

§margin_left: i32

Margin on the left edge in pixels.

§margin_right: i32

Margin on the right edge in pixels.

§gap_row: i32

Row gap (spacing between rows / cross-axis tracks) in pixels.

§gap_col: i32

Column gap (spacing between columns / main-axis tracks) in pixels.
