#
IntrinsicSize

source

pub(all) struct IntrinsicSize {
  min_width : Double
  max_width : Double
  min_height : Double
  max_height : Double
}

Intrinsic size measurement result

#
IntrinsicSize::default

source

fn IntrinsicSize::default() -> IntrinsicSize

Default intrinsic size for leaf nodes without measure function Matches Taffy behavior: empty/unmeasured nodes have zero intrinsic size

#
Layout

source

pub(all) struct Layout {
  id : String
  x : Double
  y : Double
  width : Double
  height : Double
  margin : @mizchi/css/values.Rect
Rect[Double]
  padding : @mizchi/css/values.Rect
Rect[Double]
  border : @mizchi/css/values.Rect
Rect[Double]
  overflow_x : @mizchi/css/values.Overflow
Overflow
  overflow_y : @mizchi/css/values.Overflow
Overflow
  scroll_width : Double
  scroll_height : Double
  children : Array[Layout]
  text : String?
}

Complete layout result for a node

#
Layout::to_bounding_rect

source

fn Layout::to_bounding_rect(self : Layout) -> @mizchi/css/values.BoundingRect
BoundingRect

#
LayoutContext

source

pub(all) struct LayoutContext {
  available_width : Double
  available_height : Double?
  sizing_mode : SizingMode
  viewport_width : Double
  viewport_height : Double
  stretch_width : Bool
  stretch_height : Bool
}

Context for layout computation

#
LayoutResult

source

pub(all) struct LayoutResult {
  layout : Layout
  warnings : Array[LayoutWarning]
}

Result of layout computation with warnings

#
LayoutWarning

source

pub(all) enum LayoutWarning {
  UnsupportedFloat(String)
  UnsupportedPosition(String)
  UnsupportedDisplay(String)
} derive(@moonbitlang/core/debug.Debug
Debug)

Warnings emitted during layout computation

impl Show for LayoutWarning

#
MeasureFunc

source

pub(all) struct MeasureFunc {
  func : (Double, Double) -> IntrinsicSize
}

Measure function type - called to determine intrinsic size of a node Parameters: (available_width, available_height) -> IntrinsicSize

#
SizingMode

source

pub(all) enum SizingMode {
  Definite
  MaxContent
} derive(Eq)

Sizing mode for layout computation Definite: Use available space (normal flow) MaxContent: Use intrinsic max-content (shrink-to-fit)
