Struct Context 

pub struct Context<'a> {
    pub sheets: HashMap<String, &'a Sheet>,
    pub pivot_tables: &'a [PivotTable],
    pub sheet_order: Vec<String>,
}

Context for evaluating expressions, containing references to other sheets

Fields

sheets: HashMap<String, &'a Sheet>

Map of sheet names to sheet references for cross-sheet lookups

pivot_tables: &'a [PivotTable]

Every pivot table in the workbook, so GETPIVOTDATA can resolve a rendered pivot’s destination cell back to its definition. Pivot tables are workbook-level (like Context.sheets’ cross-sheet lookups), not sheet-scoped, so this lives here rather than on Sheet itself.

sheet_order: Vec<String>

Sheet names in true workbook order, so SHEET() can report a real ordinal. sheets is an unordered HashMap, which is why this is tracked separately rather than derived from it – true order only exists one layer up, in visi’s WorkbookManager::sheets (a Vec), which populates this when building the context.

Implementations

impl<'a> Context<'a>

pub fn new() -> Self

Create a new empty context

pub fn add_table(&mut self, name: String, sheet: &'a Sheet)

Add a sheet to the context for lookup during evaluation

Trait Implementations

impl<'a> Default for Context<'a>

fn default() -> Context<'a>

Returns the “default value” for a type.
