Enum CellValue 

pub enum CellValue {
    String(String),
    Number(f64),
    Integer(i64),
    Boolean(bool),
    DateTime(i64),
    Empty,
}

A strongly-typed cell value that can represent different data types

This enum provides type safety for cell values, allowing the codebase to distinguish between strings, numbers, booleans, dates, and empty values. This eliminates the need for repeated string parsing and improves performance.

Variants

String(String)

String data

Number(f64)

Numeric data (float)

Integer(i64)

Integer data (for exact precision when needed)

Boolean(bool)

Boolean data

DateTime(i64)

Date/time data (stored as timestamp)

Empty

Empty/null value

Implementations

impl CellValue

pub fn string(s: impl Into<String>) -> Self

Create a String cell value

pub fn number(n: f64) -> Self

Create a Number cell value

pub fn integer(i: i64) -> Self

Create an Integer cell value

pub fn boolean(b: bool) -> Self

Create a Boolean cell value

pub fn datetime(timestamp: i64) -> Self

Create a DateTime cell value from timestamp

pub fn empty() -> Self

Create an Empty cell value

pub fn is_empty(&self) -> bool

Check if the value is empty

pub fn is_numeric(&self) -> bool

Check if the value is numeric (Number or Integer)

pub fn as_str(&self) -> Option<&str>

Get the value as a string reference

pub fn as_number(&self) -> Option<f64>

Get the value as a number (f64)

Returns Some(f64) for Number and Integer values, None otherwise

pub fn as_bool(&self) -> Option<bool>

Get the value as a boolean

pub fn to_display_string(&self) -> String

Convert to display string

pub fn parse(s: &str) -> Self

Parse a string into the most appropriate CellValue type

Attempts to parse the string as:

1. Empty -> Empty
2. Boolean (“true”/“false”) -> Boolean
3. Integer -> Integer
4. Float -> Number
5. Otherwise -> String

pub fn from_string_with_type(s: &str, type_hint: Option<&DataType>) -> Self

Convert from string representation with type hint

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() -> Self

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<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<i64> for CellValue

fn from(i: i64) -> Self

Converts to this type from the input type.

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.
