Enum CellWidth 

pub enum CellWidth {
    Continuation,
    Single,
    Wide,
}

How many terminal columns a Cell covers, modeling East Asian double-width glyphs and emoji, which occupy two columns.

This crate does not compute width — that needs the Unicode database, which a zero-dependency crate cannot own. Callers pick the width (e.g. from the uwidth crate); the renderers here honor whatever they are given.

Variants

Continuation

The right half of the double-width glyph to its left: it carries no character of its own and is never emitted, because the terminal advances the cursor by two columns when it draws the lead glyph.

Single

A normal single-width cell (the common case, and the default).

Wide

The left half (lead) of a double-width glyph; the cell holds the character, and the cell immediately to its right should be a CellWidth::Continuation.

Implementations

impl CellWidth

pub const fn columns(self) -> usize
