Module data 

Core data model for the grid: cell values, columns, and the rectangular GridData container.

GridData is intentionally simple — a column list paired with a Vec of rectangular rows of CellValue. It carries no rendering, sorting, or filtering state: those live on crate::grid::GridState. Keeping the data layer pure makes it reusable from outside the widget (export pipelines, server-side previews, test fixtures).

CellValue does not implement Eq/Ord because CellValue::Decimal holds an f64. Use compare_cells when you need a deterministic total ordering that handles NaN and mixed numeric kinds deliberately rather than collapsing to Equal.

Structs

Column

A single column declaration.

GridData

Rectangular grid data: rows.len() rows each of length columns.len().

Enums

CellValue

A single cell value.

ColumnKind

Declared column kind. Drives the default crate::config::ResolvedColumnFormat when no crate::config::ColumnOverride is supplied.

GridDataError

Error returned when GridData cannot be constructed or validated because at least one row’s length disagrees with the column count.

Functions

compare_cells

Total deterministic ordering for CellValue.

sample_data

A handful of synthetic ledger-style rows for examples and the sample application. Kept here so examples have a known shape without pulling in a separate data file. Production code should construct GridData directly.
