Struct InnerCoordinator 

pub struct InnerCoordinator<'a> { /* private fields */ }

Inner coordinator that wraps the layout node’s intrinsic content (MeasurePolicy).

This is analogous to Jetpack Compose’s InnerNodeCoordinator.

Implementations

impl<'a> InnerCoordinator<'a>

pub fn new( measure_policy: Rc<dyn MeasurePolicy>, measurables: &'a [Box<dyn Measurable>], result_holder: Rc<RefCell<Option<MeasureResult>>>, ) -> Self

Creates a new inner coordinator with the given measure policy and children.

Trait Implementations

impl<'a> Measurable for InnerCoordinator<'a>

fn measure(&self, constraints: Constraints) -> Box<dyn Placeable>

Measures the child with the provided constraints, returning a Placeable.

fn min_intrinsic_width(&self, height: f32) -> f32

Returns the minimum width achievable for the given height.

fn max_intrinsic_width(&self, height: f32) -> f32

Returns the maximum width achievable for the given height.

fn min_intrinsic_height(&self, width: f32) -> f32

Returns the minimum height achievable for the given width.

fn max_intrinsic_height(&self, width: f32) -> f32

Returns the maximum height achievable for the given width.

fn flex_parent_data(&self) -> Option<FlexParentData>

Returns flex parent data if this measurable has weight/fill properties. Default implementation returns None (no weight).

impl<'a> NodeCoordinator for InnerCoordinator<'a>

fn total_content_offset(&self) -> Point

Returns the accumulated placement offset from this coordinator down through the wrapped chain (inner-most coordinator).
