Enum Value 

pub enum Value {
    Empty,
    String(String),
    Number(f64),
    Bool(bool),
    DateNumber(f64),
    Rows(RowsHandle),
    Map(MapHandle),
    List(ListHandle),
}

Variants

Empty

String(String)

Number(f64)

Bool(bool)

DateNumber(f64)

An Excel serial number whose source cell carried a date / datetime numFmt. Behaves like Number for arithmetic and numeric comparison; its canonical string form is the ISO YYYY-MM-DD / YYYY-MM-DDTHH:MM:SS representation per ADR-0017. Output cells write the raw serial — the format is reapplied by the consuming spreadsheet.

Rows(RowsHandle)

All source rows visible to the active expansion block. Used for row aggregates. Not emitted as a cell value.

Map(MapHandle)

Reserved-sheet dictionary value (__config__, __inputs__, __lists__). Looked up via <ns>[key] in expressions.

List(ListHandle)

A list — typically a column of __lists__. Used by the in and !in operators inside @filter.

Implementations

impl Value

pub fn canonical(&self) -> String

Canonical string form per ADR-0009 (xl3 TS canonicalString mirror). Used when a value is substituted into a mixed text cell — e.g. "Hello {{ [Name] }}" — so cross-impl rendering of booleans / numbers / empty values is stable.

pub fn from_calamine(d: &CalamineData) -> Value

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Value

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Value

fn eq(&self, other: &Value) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
