pub enum UnicodeVersion {
    Unicode9,
    Unicode10,
    Unicode11,

    Unicode14,
    Unicode15,
    Unicode15_1,
    Unicode16,
    Auto,
}

Unicode version for width calculation tables.

Different Unicode versions have different character width assignments, particularly for newly added emoji and other characters.

Implementations

impl UnicodeVersion

pub fn is_auto(&self) -> bool

Returns true if this version is Auto (use latest)

pub fn version_tuple(&self) -> Option<(u8, u8)>

Returns the version number as a tuple (major, minor)

pub fn version_string(&self) -> &'static str

Returns a human-readable version string

Trait Implementations

impl Clone for UnicodeVersion

fn clone(&self) -> UnicodeVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnicodeVersion

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

Formats the value using the given formatter.

impl Default for UnicodeVersion

fn default() -> UnicodeVersion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UnicodeVersion

fn deserialize<__D>( __deserializer: __D, ) -> Result<UnicodeVersion, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UnicodeVersion

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

impl Serialize for UnicodeVersion

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for UnicodeVersion

impl Eq for UnicodeVersion

impl StructuralPartialEq for UnicodeVersion
