Struct DataColumn 

pub struct DataColumn {
    pub id: u64,
    pub name: String,
    /* private fields */
}

One column of a sheet: the raw text, the computed values, the compiled formulas and the styles, as parallel per-row vectors.

Invariant

src, data, compiled_src and styles must all stay the same length – row r of the column is entry r of each. Nothing enforces this; the row and column insert/delete paths in Sheet maintain it by hand, and Sheet::setup_after_deserialization restores it after a load, since only src and styles are persisted. Mutating one of these vectors directly will break it.

dirty_indices is not part of that invariant – it is a queue of rows awaiting recomputation, and is emptied by Sheet::commit.

Fields

id: u64

Identifier, stable across renames and repositioning. Compiled formulas refer to a column by this rather than by name or position.

name: String

Display name, empty unless one was set.

Implementations

impl DataColumn

pub fn new(size: usize) -> Self

A column of size empty rows, with every parallel vector sized to match and a freshly generated id.

pub fn len(&self) -> usize

Rows in the column. Every parallel vector has this length.

pub fn is_empty(&self) -> bool

Whether the column has no rows.

pub fn src(&self, row: usize) -> Option<&str>

The raw text of a cell, exactly as typed, or None past the end.

pub fn value(&self, row: usize) -> Option<ResultData>

The computed value of a cell, or None past the end.

Reflects the last Sheet::commit; a cell edited since then still reads as its old value.

pub fn values(&self) -> &ColumnData

The whole value column, for callers that want to work with the typed representation rather than row by row.

pub fn compiled(&self, row: usize) -> Option<&CompiledFormula>

A cell’s compiled formula, or None past the end. A cell holding a literal has an empty one rather than no entry.

pub fn style(&self, row: usize) -> Option<&CellStyle>

A cell’s style, or None if it has none or is past the end.
