Struct EdgeSizes 

pub struct EdgeSizes {
    pub top: f32,
    pub right: f32,
    pub bottom: f32,
    pub left: f32,
}

Represents the four edges of a box for properties like margin, padding, border.

Fields

top: f32

right: f32

bottom: f32

left: f32

Implementations

impl EdgeSizes

pub fn horizontal_sum(&self) -> f32

Sum of horizontal edges (left + right).

pub fn vertical_sum(&self) -> f32

Sum of vertical edges (top + bottom).

pub const fn main_start(&self, wm: LayoutWritingMode) -> f32

Returns the size of the edge at the start of the main/block axis.

pub const fn main_end(&self, wm: LayoutWritingMode) -> f32

Returns the size of the edge at the end of the main/block axis.

pub fn main_sum(&self, wm: LayoutWritingMode) -> f32

Returns the sum of the start and end sizes on the main/block axis.

pub const fn cross_start(&self, wm: LayoutWritingMode) -> f32

Returns the size of the edge at the start of the cross/inline axis.

pub const fn cross_end(&self, wm: LayoutWritingMode) -> f32

Returns the size of the edge at the end of the cross/inline axis.

pub fn cross_sum(&self, wm: LayoutWritingMode) -> f32

Returns the sum of the start and end sizes on the cross/inline axis.

pub const fn line_over(&self, wm: LayoutWritingMode) -> f32

Returns the line-over edge (line-relative block-axis start).

Per CSS Writing Modes L4 §6.3, the line-over side is top in horizontal-tb and right in both vertical writing modes. Unlike Self::main_start (a physical block-axis accessor), this is the line-relative over side and coincides with main_start only in horizontal-tb.

pub const fn line_under(&self, wm: LayoutWritingMode) -> f32

Returns the line-under edge (line-relative block-axis end).

Per CSS Writing Modes L4 §6.3, the line-under side is bottom in horizontal-tb and left in both vertical writing modes.

pub fn line_over_under_sum(&self, wm: LayoutWritingMode) -> f32

Returns the sum of the line-over and line-under edges.

pub const fn inline_start( &self, wm: LayoutWritingMode, dir: StyleDirection, ) -> f32

Returns the flow-relative inline-start edge.

The inline-start side is line-left (see Self::cross_start) when the inline base direction is LTR, and line-right (see Self::cross_end) when it is RTL. This is the direction-aware counterpart that cross_start/cross_end (which are direction-blind line-left/line-right) cannot express on their own.

pub const fn inline_end( &self, wm: LayoutWritingMode, dir: StyleDirection, ) -> f32

Returns the flow-relative inline-end edge.

The inline-end side is line-right when the inline base direction is LTR, and line-left when it is RTL.

pub fn inline_sum(&self, wm: LayoutWritingMode, dir: StyleDirection) -> f32

Returns the sum of the inline-start and inline-end edges.

Direction-independent (start + end covers the whole inline axis), but takes dir for call-site symmetry with the individual accessors.
