Enum ItemAlignment 

pub enum ItemAlignment {
    Start,
    Center,
    End,
    Nearest,
}

Where ScrollController::scroll_to_item lands a row in the viewport.

Every alignment is clamped to the list’s [0, max_offset] range, so a row too near either end of the content to reach the requested position stops at the edge instead (the first row can never be centered).

Variants

Start

The row’s top edge at the viewport’s top edge.

Center

The row’s center at the viewport’s center.

End

The row’s bottom edge at the viewport’s bottom edge.

Nearest

The least movement that shows the whole row: nothing at all when it is already fully visible, ItemAlignment::Start when it sits above the viewport (or is taller than it), ItemAlignment::End when below.
