Supported languages for text analysis.

Variants are intentionally ordered for indexed access in detect_language. The repr(u8) is required for safe conversion from index to enum variant.

Implementations

impl Language

pub fn is_cjk(&self) -> bool

Returns true if this is a CJK (Chinese, Japanese, Korean) language.

pub fn is_rtl(&self) -> bool

Returns true if this is a right-to-left language (Arabic, Hebrew).

pub fn uses_latin_capitalization(&self) -> bool

Returns true if this language uses the Latin script with sentence-initial capitalization (English, French, Spanish, German, Italian, Portuguese).

Used to gate capitalization adjustments in pronoun rewriting: only these languages capitalize the first word of a sentence, so replacing a sentence-initial pronoun with a proper noun needs case adjustment.

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

Get ISO 639-1 language code (2-letter).

impl Language

pub fn from_code(code: &str) -> Option<Language>

Parse from ISO 639-1/639-3 code or English name.

Returns None for unrecognized codes (rather than silently defaulting).

use anno::Language;

assert_eq!(Language::from_code("en"), Some(Language::English));
assert_eq!(Language::from_code("de"), Some(Language::German));
assert_eq!(Language::from_code("english"), Some(Language::English));
assert_eq!(Language::from_code("xyz"), None);

Trait Implementations

impl Clone for Language

fn clone(&self) -> Language

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Language

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

Formats the value using the given formatter.

impl Display for Language

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

Formats the value using the given formatter.

impl Hash for Language

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

where __H: Hasher,

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 Language

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