A private trait which allows us to add extra convenience methods to types which implement LayoutTree without making those methods public.

Provided Methods

fn measure_child_size( &mut self, node_id: NodeId, known_dimensions: Size<Option<f32>>, parent_size: Size<Option<f32>>, available_space: Size<AvailableSpace>, sizing_mode: SizingMode, axis: AbsoluteAxis, vertical_margins_are_collapsible: Line<bool>, ) -> f32

Compute the size of the node given the specified constraints

fn perform_child_layout( &mut self, node_id: NodeId, known_dimensions: Size<Option<f32>>, parent_size: Size<Option<f32>>, available_space: Size<AvailableSpace>, sizing_mode: SizingMode, vertical_margins_are_collapsible: Line<bool>, ) -> LayoutOutput

Perform a full layout on the node given the specified constraints

fn calc(&self, val: *const (), basis: f32) -> f32

Alias to resolve_calc_value with a shorter function name

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
