Trait layout_engine::Layout

pub trait Layout {
    // Required methods
    fn width_for_height(&self, height: usize) -> MinimumNatural<usize>;
    fn height_for_width(&self, width: usize) -> MinimumNatural<usize>;
    fn prefered_size(&self) -> MinimumNatural<Vec2>;

}

A layout trait

It uses height to width management like Gtk

Required Methods

fn width_for_height(&self, height: usize) -> MinimumNatural<usize>

Given a height, how much width would this like to have at minimum.

fn height_for_width(&self, width: usize) -> MinimumNatural<usize>

Given a width, how much height would this like to have at minimum.

fn prefered_size(&self) -> MinimumNatural<Vec2>

What would this widget like to have in an ideal world.

fn prefered_size_of_container(&self, container: Vec2) -> MinimumNatural<Vec2>

How would this widget choose to allocate itself given the parent’s size
