Struct Change 

pub struct Change {
    pub sheet: String,
    pub addr: Address,
    pub old: Value,
    pub new: Value,
}

One cell whose evaluated value a recalc changed.

Returned (in deterministic order) by Workbook::recalc and Workbook::recalc_incremental: the “change events” of v1, delivered as a value rather than via a callback (value-object ADR). Ordering is pinned — by sheet tab index, then row, then column (scope ADR Decision 3) — so the change list is reproducible.

Fields

sheet: String

The sheet’s name (its authored casing).

addr: Address

The recomputed cell’s address.

old: Value

The cell’s value before this recalc (the stored result).

new: Value

The cell’s value after this recalc.
