Struct SpreadsheetColumn 

pub struct SpreadsheetColumn { /* private fields */ }

A spreadsheet column converter, optionally zero-based.

Implementations

impl SpreadsheetColumn

pub fn new() -> Self

A one-based converter (1 → A).

pub fn zero_based() -> Self

A zero-based converter (0 → A).

pub fn from_int(&self, n: i64) -> Result<String, Error>

Convert a column number to its letter name.

Errors

Returns Error::Negative for negative input, or Error::ZeroNotAllowed for 0 in one-based mode.

pub fn from_str(&self, column: &str) -> Result<i64, Error>

Convert a column letter name to its number.

Errors

Returns Error::InvalidString if column is empty or contains a non-letter.

Trait Implementations

impl Clone for SpreadsheetColumn

fn clone(&self) -> SpreadsheetColumn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SpreadsheetColumn

impl Debug for SpreadsheetColumn

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

Formats the value using the given formatter.

impl Default for SpreadsheetColumn

fn default() -> SpreadsheetColumn

Returns the “default value” for a type.

impl Eq for SpreadsheetColumn

impl PartialEq for SpreadsheetColumn

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