Enum Flex 

pub enum Flex {
    Start,
    End,
    Center,
    SpaceBetween,
    SpaceAround,
}

How leftover space is placed along the split axis, once Constraints are resolved.

Only matters when the resolved pane sizes sum to less than area’s length; passed to split_v_flex/split_h_flex.

split_v/split_h always behave like Start: any leftover space trails after the last pane, unclaimed. This matches their existing documented behavior, so adding Flex does not change them.

Variants

Start

Panes are packed at the start of the area; leftover space trails after the last pane. The default, and what split_v/split_h use.

End

Panes are packed at the end of the area; leftover space leads before the first pane.

Center

Leftover space is split evenly before and after the panes.

SpaceBetween

Leftover space is distributed as gaps between panes (none before the first or after the last). No-op with fewer than two panes.

SpaceAround

Leftover space is distributed as equal-width gaps around every pane, including before the first and after the last.
