Enum RowSelection 

pub enum RowSelection {
    None,
    All,
    Partial {
        start: (LineSource, usize),
        end: (LineSource, usize),
    },
}

How far a selection extends within one row.

Variants

None

Not selected at all.

All

Every source in the row is fully selected.

Partial

Runs from start to end, which may be in different sources.

This is the shape the first version got wrong: it could name only one source, so a boundary landing in the gutter left the rest of that row unselected. Dragging left and then up — which puts the start of the selection in a gutter — highlighted the nick and not the message, which reads as the selection being inverted.

Fields

start: (LineSource, usize)

end: (LineSource, usize)
