Enum CellValue 

pub enum CellValue {
    Empty,
    Bool(bool),
    Number(f64),
    String(String),
    Formula {
        expr: String,
        result: Option<Box<CellValue>>,
    },
    Date(f64),
    Error(String),
    RichString(Vec<RichTextRun>),
}

Represents the value of a cell.

Variants

Empty

No value (empty cell).

Bool(bool)

Boolean value.

Number(f64)

Numeric value (integers are stored as f64 in Excel).

String(String)

String value.

Formula

Formula with optional cached result.

Fields

expr: String

result: Option<Box<CellValue>>

Date(f64)

A date/time value stored as an Excel serial number. Integer part = days since 1899-12-30 (Excel epoch). Fractional part = time of day (0.5 = noon).

Error(String)

Error value (e.g. #DIV/0!, #N/A, #VALUE!).

RichString(Vec<RichTextRun>)

Rich text: multiple formatted runs within a single cell.

Trait Implementations

impl Clone for CellValue

fn clone(&self) -> CellValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CellValue

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

Formats the value using the given formatter.

impl Default for CellValue

fn default() -> CellValue

Returns the “default value” for a type.

impl Display for CellValue

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

Formats the value using the given formatter.

impl From<&str> for CellValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<NaiveDate> for CellValue

fn from(date: NaiveDate) -> Self

Converts to this type from the input type.

impl From<NaiveDateTime> for CellValue

fn from(datetime: NaiveDateTime) -> Self

Converts to this type from the input type.

impl From<String> for CellValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<bool> for CellValue

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f64> for CellValue

fn from(n: f64) -> Self

Converts to this type from the input type.

impl From<i32> for CellValue

fn from(n: i32) -> Self

Converts to this type from the input type.

impl From<i64> for CellValue

fn from(n: i64) -> Self

impl PartialEq for CellValue

fn eq(&self, other: &CellValue) -> 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.
