pub enum GraphemeClusterMode {
    Unicode,
    WcWidth,
    NoZwj,
}

Variants

Unicode

Support grapheme clustering

WcWidth

Doesn’t support shaping

NoZwj

Implementations

impl GraphemeClusterMode

pub fn from_env() -> Self

Use environment variables to guess current mode

pub fn width(&self, s: &str) -> u16

Grapheme with / number of columns

Trait Implementations

impl Clone for GraphemeClusterMode

fn clone(&self) -> GraphemeClusterMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphemeClusterMode

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

Formats the value using the given formatter.

impl PartialEq for GraphemeClusterMode

fn eq(&self, other: &GraphemeClusterMode) -> 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.
