    pub terminal: TerminalType,
    /* private fields */
}

Character width table with caching

Fields

cjk: u8

Width for CJK characters

emoji: u8

Width for emoji

nerd_font: u8

Width for nerd font icons

terminal: TerminalType

Detected terminal type

Implementations

impl CharWidthTable

pub fn new() -> Self

Create a new width table with defaults

pub fn detect() -> Self

Detect character widths from terminal environment

This detects the terminal type from environment variables and sets appropriate default widths for emoji, CJK, and nerd fonts.

Note: This is a heuristic based on known terminal behaviors. For precise width detection, some terminals support querying character widths via escape sequences, but this is not universally supported and may cause issues in some environments.

pub fn for_terminal(terminal: TerminalType) -> Self

Create for a specific terminal type

pub fn width(&self, ch: char) -> u8

Get width of a character

pub fn set_override(&mut self, ch: char, width: u8)

Override width for specific character

pub fn with_cjk(self, width: u8) -> Self

Set CJK width

pub fn with_emoji(self, width: u8) -> Self

Set emoji width

pub fn with_nerd_font(self, width: u8) -> Self

Set nerd font width

Trait Implementations

impl Default for CharWidthTable

fn default() -> Self

Returns the “default value” for a type.
