Enum WidthMode 

pub enum WidthMode {
    Standard,
    CjkAmbiguousWide,
}

Unicode character width measurement mode for search results.

Controls how display column offsets are computed — in particular for East Asian Ambiguous characters whose width differs between CJK and Western terminals.

Variants

Standard

Standard Unicode width: EA Ambiguous characters are single-width (1 cell).

CjkAmbiguousWide

CJK-aware width: EA Ambiguous characters are double-width (2 cells).

Implementations

impl WidthMode

pub fn char_width(self, ch: char) -> usize

Compute the terminal display width of a single Unicode scalar.

pub fn str_width(self, s: &str) -> usize

Compute the display width of a string by summing per-character widths.

Trait Implementations

impl Clone for WidthMode

fn clone(&self) -> WidthMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WidthMode

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

Formats the value using the given formatter.

impl Default for WidthMode

fn default() -> WidthMode

Returns the “default value” for a type.

impl Hash for WidthMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WidthMode

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

Tests for self and other values to be equal, and is used by ==.

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

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