Struct RowDelta 

pub struct RowDelta {
    pub start: usize,
    pub replaced: usize,
    pub len: usize,
    pub src_shift: i64,
}

Where two frames’ rows differ: the span of the old rows a span of the new ones replaces, and the offset the rows after it moved by. See row_delta.

Fields

start: usize

The first row that differs — the length of the common prefix, which is where the new span begins in both the old rows and the new.

replaced: usize

How many of the old rows, from start, the new span replaces.

len: usize

How many new rows stand in their place.

src_shift: i64

The byte offset every source offset in a row after the span moved by: the rows after the span are the old ones with this added to each offset they carry. Zero when nothing moved, and when no row after the span carries an offset to move.
