Struct RowDrop 

pub struct RowDrop {
    pub target: usize,
    pub position: DropPosition,
    pub destination: usize,
}

The (target, position) pair a pointer drop would have carried, plus where the moved item ends up.

See the module documentation for why the commit travels as a drop rather than as a destination index.

Fields

target: usize

The row the drop lands on.

position: DropPosition

Which side of target it lands on.

destination: usize

Where the moved row ends up once the source has applied it.

Implementations

impl RowDrop

pub fn between(from: usize, destination: usize) -> Self

The drop that moves the item at from to destination.

Before when the item travels backwards, After when it travels forwards — the same two gaps a drag would have released over, so the source’s own index arithmetic (which shifts by one when the removal is above the insertion point) is exercised unchanged.

Public and destination-based, not only OrderedMove-based, because a 2-D grid also moves a tile by a whole row at a time and that is not one of the four named moves.
