Enum CellExport 

#[non_exhaustive]
pub enum CellExport<R: GridRow> {
    Raw(RawCells),
    Displayed(DisplayedCells),
    Custom(Arc<dyn CellExporter<R>>),
}

The cell exporter of a grid: the built-in exporters dispatched statically, plus a custom one.

The default is Raw(RawCells::new()). A custom exporter is called through its Arc without allocating per cell. For example, raw values for a spreadsheet in a Russian locale:

use std::sync::Arc;

use gpui_kit_grid::{CellExport, CellExporter, CellValue, ExportCell, GridRow, RawCells};

/// Raw values with a decimal comma and `ИСТИНА` or `ЛОЖЬ`.
struct RussianSpreadsheetCells(RawCells);

impl<R: GridRow> CellExporter<R> for RussianSpreadsheetCells {
    fn write_cell(&self, cell: &ExportCell<'_, R>, out: &mut String) {
        match cell.value() {
            CellValue::Bool(value) => out.push_str(if value { "ИСТИНА" } else { "ЛОЖЬ" }),
            _ => self.0.write_cell(cell, out),
        }
    }
}

fn russian_spreadsheet_cells<R: GridRow>() -> CellExport<R> {
    CellExport::Custom(Arc::new(RussianSpreadsheetCells(
        RawCells::new().with_decimal_separator(','),
    )))
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Raw(RawCells)

Raw values that spreadsheets parse back.

Displayed(DisplayedCells)

The text painted in the cell.

Custom(Arc<dyn CellExporter<R>>)

An application exporter.
