Cell

Struct Cell 

Source
pub struct Cell {
    pub ch: char,
    pub fg: Color,
    pub bg: Option<Color>,
    pub attrs: u8,
}
Expand description

A single rendered cell: a character plus optional color attributes.

Footprint is bounded by AD-011 to ~16 bytes on 64-bit targets:

  • ch: char — 4 bytes
  • fg: Color — 4 bytes (variant tag + 3-byte payload for Rgb)
  • bg: Option<Color> — 5 bytes (tag + 4-byte Color)
  • attrs: u8 — 1 byte (bold / underline / reverse bitfield)

The remaining ~2 bytes are alignment padding.

Fields§

§ch: char

Glyph character at this cell.

§fg: Color

Foreground color.

§bg: Option<Color>

Optional background color (None = terminal default bg).

§attrs: u8

SGR attribute bitfield: bit 0 = bold, bit 1 = underline, bit 2 = reverse.

Implementations§

Source§

impl Cell

Source

pub fn new(ch: char) -> Self

Construct a cell with the given glyph; default foreground (white), no background, no attributes.

Source

pub fn blank() -> Self

Blank cell — a space with default colors.

Source

pub fn is_blank(&self) -> bool

true if the cell is visually blank (space character).

Used by [apply_crop] to detect all-blank rows/columns. Color and attribute bits are ignored — a colored space is still blank.
