Struct TuiCell 

pub struct TuiCell {
    pub grapheme: String,
    pub fg: [f32; 3],
    pub bg: Option<[f32; 3]>,
    pub bold: bool,
    pub italic: bool,
    pub underline: UnderlineStyle,
    pub strikethrough: bool,
    pub link: Option<Arc<String>>,
}

A single rendered cell in a TUI screen grid.

Fields

grapheme: String

Full grapheme cluster (base + combining/ZWJ sequence). A single terminal cell may contain multiple codepoints, e.g. 👨‍👩‍👧 (ZWJ family), 👋🏽 (skin-tone modifier), 1️⃣ (keycap), 🇯🇵 (regional-indicator flag).

fg: [f32; 3]

Foreground RGB color (linear, 0.0–1.0).

bg: Option<[f32; 3]>

Background RGB color. None means default background (transparent/Base).

bold: bool

italic: bool

underline: UnderlineStyle

strikethrough: bool

link: Option<Arc<String>>

OSC 8 hyperlink URI (shared via Arc because runs of cells share the same link).

Implementations

impl TuiCell

pub fn first_char(&self) -> char

First codepoint of the grapheme, or \0 if empty. Useful for single-codepoint classification (whitespace/null/box-drawing).

pub fn is_null(&self) -> bool

True if the cell is a null spacer (wide-char follow-up) or blank.
