Enum Dependency 

pub enum Dependency {
    Local(CellRef),
    LocalColumn(usize),
    Remote {
        sheet: String,
        cell: CellRef,
    },
    RemoteColumn {
        sheet: String,
        col: usize,
    },
}

Something a formula reads, and therefore an edge in the recalculation graph.

The local/remote split is load-bearing. Sheet::commit propagates through the Local variants only – a sheet cannot reach into its neighbors, so a remote edge it finds is recorded but not followed. Chasing those is WorkbookManager::evaluate’s job, which marks every sheet dirty and runs a fixed number of passes over the workbook; a cross-sheet chain deeper than that number of hops will not have converged when it stops.

Remote variants key on the sheet name rather than its id, since that is what a formula’s text carries and what Context is indexed by.

Variants

Local(CellRef)

A cell on the same sheet.

LocalColumn(usize)

A whole column on the same sheet, by 0-based position.

Remote

A cell on another sheet.

Fields

sheet: String

Name of the sheet the cell is on.

cell: CellRef

The cell, on that sheet.

RemoteColumn

A whole column on another sheet.

Fields

sheet: String

Name of the sheet the column is on.

col: usize

Column index, 0-based.
