Enum ResultData 

pub enum ResultData {
    None,
    Boolean(bool),
    Integer(i64),
    Float(f64),
    String(String),
    List(Vec<ResultData>),
    Dict(Vec<(ResultData, ResultData)>),
    Error(String),
}

What a cell holds once it has been evaluated.

There is deliberately no date variant. As in Excel, a date is a plain numeric serial and the notation it was typed in lives on the cell, as CellStyle::num_format – so ISNUMBER is true for a date, SUM counts it, and every numeric path works on it untouched. Only rendering consults the format, through Sheet::get_display_string.

An Excel error is a value, not a Rust error: =1/0 evaluates successfully to Error("#DIV/0!"). See EngineError for the failures that are not values.

Variants

None

A blank cell. Coerces to 0 or "" depending on what reads it.

Boolean(bool)

TRUE or FALSE.

Integer(i64)

A whole number.

Float(f64)

A number that is not a whole number, or one too large for an i64. A date is a Float holding its Excel serial.

String(String)

Text.

List(Vec<ResultData>)

An ordered sequence, for the engine-specific functions that return one. Not an Excel array.

Dict(Vec<(ResultData, ResultData)>)

Key/value pairs, for the engine-specific functions that return them.

Error(String)

An Excel error value, held as its code: #DIV/0!, #VALUE!, #N/A.
