Implementations

impl LayoutBoxes

pub fn width(&self) -> f32

Returns the maximum width among all boxes.

pub fn height(&self) -> f32

Returns the total height (sum of all boxes).

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn iter(&self) -> impl Iterator<Item = &BoxModel>

Returns an iterator over references to the contained BoxModels.

The iteration order is:

• empty for LayoutBoxes::None
• a single element for LayoutBoxes::Single
• the order of elements in the inner vector for LayoutBoxes::Multiple

This method provides a convenient way to iterate over all boxes regardless of the internal representation.

pub fn iter_mut(&mut self) -> impl Iterator<Item = &mut BoxModel>

Returns an iterator over mutable references to the contained BoxModels.

The iteration order is:

• empty for LayoutBoxes::None
• a single element for LayoutBoxes::Single
• the order of elements in the inner vector for LayoutBoxes::Multiple

This allows in-place modification of all boxes in a uniform way.
