Struct Calc 

pub struct Calc {
    pub graph: Graph,
    pub fixed_now: Option<f64>,
    pub circular: Vec<Key>,
    pub last_recalc_cells: usize,
    /* private fields */
}

Calculation state kept beside a workbook.

Fields

graph: Graph

fixed_now: Option<f64>

Fixed “now” for deterministic tests; None = system clock.

circular: Vec<Key>

Cells whose formulas have errors from cycles.

last_recalc_cells: usize

Implementations

impl Calc

pub fn new() -> Self

pub fn rebuild(&mut self, wb: &Workbook)

Rebuilds the graph from scratch.

pub fn recalc_all(&mut self, wb: &mut Workbook)

Recalculates every formula (F9 / Ctrl+Alt+F9, and after loading).

pub fn cells_changed(&mut self, wb: &mut Workbook, changed: &[Key])

Updates the graph for cells whose content changed and recalculates what depends on them.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Calc

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Calc

fn default() -> Self

Returns the “default value” for a type.
