Struct BoxMeasurePolicy 

pub struct BoxMeasurePolicy {
    pub content_alignment: Alignment,
    pub propagate_min_constraints: bool,
    pub layout_direction: LayoutDirection,
}

MeasurePolicy for Box layout - overlays children according to alignment.

Fields

content_alignment: Alignment

propagate_min_constraints: bool

layout_direction: LayoutDirection

Direction used to resolve start and end alignment.

Implementations

impl BoxMeasurePolicy

pub fn new( content_alignment: Alignment, propagate_min_constraints: bool, ) -> Self

Trait Implementations

impl Clone for BoxMeasurePolicy

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BoxMeasurePolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl MeasurePolicy for BoxMeasurePolicy

fn measure_hold( &self, measurables: &[Box<dyn Measurable>], constraints: Constraints, size: Size, ) -> Option<ConstraintsHold>

A box holds while every child holds under the constraints it hands on and the largest child, which sizes the box, still fits.

fn measure( &self, scope: &dyn MeasureScope, measurables: &[Box<dyn Measurable>], constraints: Constraints, ) -> MeasureResult

Runs the measurement pass with the provided children and constraints.

fn measure_into( &self, scope: &dyn MeasureScope, measurables: &[Box<dyn Measurable>], constraints: Constraints, placements: &mut Vec<Placement>, ) -> Measurement

Runs measurement into caller-owned placement storage.

fn min_intrinsic_width( &self, measurables: &[Box<dyn Measurable>], height: f32, ) -> f32

Computes the minimum intrinsic width of this policy.

fn max_intrinsic_width( &self, measurables: &[Box<dyn Measurable>], height: f32, ) -> f32

Computes the maximum intrinsic width of this policy.

fn min_intrinsic_height( &self, measurables: &[Box<dyn Measurable>], width: f32, ) -> f32

Computes the minimum intrinsic height of this policy.

fn max_intrinsic_height( &self, measurables: &[Box<dyn Measurable>], width: f32, ) -> f32

Computes the maximum intrinsic height of this policy.

impl PartialEq for BoxMeasurePolicy
