Trait Placeable 

pub trait Placeable {
    // Required methods
    fn place(&self, x: f32, y: f32);
    fn width(&self) -> f32;
    fn height(&self) -> f32;
    fn node_id(&self) -> usize;

    // Provided method
    fn content_offset(&self) -> (f32, f32) { ... }
}

Result of running a measurement pass for a single child.

Required Methods

fn place(&self, x: f32, y: f32)

Places the child at the provided coordinates relative to its parent.

fn width(&self) -> f32

Returns the measured width of the child.

fn height(&self) -> f32

Returns the measured height of the child.

fn node_id(&self) -> usize

Returns the identifier for the underlying layout node.

Provided Methods

fn content_offset(&self) -> (f32, f32)

Returns the accumulated content offset from the coordinator chain. This is used by layout modifiers (like scroll) to report where content should be positioned within this placeable’s bounds. Default is (0.0, 0.0) for no offset.
