Trait embedded_layout::layout::linear::SecondaryAlignment

pub trait SecondaryAlignment: Alignment {
    type First: Alignment;
    fn measure(prev: Size, view_size: Size) -> Size;
}

Secondary alignment is used to align views perpendicular to the placement axis.

For example, use horizontal::Right to align views to the right in a vertical linear layout.

SecondaryAlignment should be implemented by custom Alignment types, otherwise they won't be compatible with LinearLayout.

Associated Types

I.e. horizontal::Left returns the maximum width, while horizontal::LeftToRight returns the sum of the two widths.
