Struct LayoutModifierMeasureResult 

pub struct LayoutModifierMeasureResult {
    pub size: Size,
    pub placement_offset_x: f32,
    pub placement_offset_y: f32,
    pub alignment_lines: AlignmentLines,
}

Result of a layout modifier measurement operation.

Unlike MeasureResult which is for MeasurePolicy (multiple children), this type is specifically for layout modifiers which wrap a single piece of content and need to specify where that wrapped content should be placed.

Fields

size: Size

The size this modifier will occupy.

placement_offset_x: f32

The offset at which to place the wrapped content relative to the top-left corner of this modifier’s bounds. For example, PaddingNode returns (padding.left, padding.top) here to offset the child by the padding amount.

placement_offset_y: f32

The vertical offset of the wrapped content, as placement_offset_x.

alignment_lines: AlignmentLines

Explicit alignment lines. Unspecified lines are inherited from wrapped content.

Implementations

impl LayoutModifierMeasureResult

pub fn new( size: Size, placement_offset_x: f32, placement_offset_y: f32, ) -> LayoutModifierMeasureResult

A modifier of size that places its content at the offset.

pub fn with_size(size: Size) -> LayoutModifierMeasureResult

Creates a result with zero placement offset (wrapped content placed at 0,0).

pub fn with_alignment_lines( self, alignment_lines: AlignmentLines, ) -> LayoutModifierMeasureResult

Overrides the wrapped content’s alignment lines in this modifier’s coordinates.
