pub fn data(self, ch: char) -> Self

impl Cell

pub const BLANK: Cell = _

A blank cell with default formatting.

Trait Implementations

impl Clone for Cell

fn clone(&self) -> Cell

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cell

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

Formats the value using the given formatter.

impl Formatted for Cell

fn get_fmt(&self) -> &Format

fn get_fmt_mut(&mut self) -> &mut Format

impl PartialEq for Cell

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Eq for Cell
