Crate unic [−] [src]
UNIC: Unicode and Internationalization Crates for Rust
The unic
super-crate (this) is a collection of all UNIC components, providing
an easy way of access to all functionalities, when all or many are needed,
instead of importing components one-by-one, and ensuring all components
imported are compatible in algorithms and consistent data-wise.
Components
ucd
: Unicode Character Database.bidi
: Unicode Bidirectional Algorithm (USA#9).normal
: Unicode Normalization Forms (USA#15).idna
: Unicode IDNA Compatibility Processing (UTS#46).
A Basic Example
extern crate unic; use unic::bidi::BidiInfo; use unic::normal::StrNormalForm; use unic::ucd::{Age, BidiClass, CharAge, CharBidiClass, StrBidiClass, UnicodeVersion}; use unic::ucd::normal::compose; fn main() { // Age assert_eq!(Age::of('A'), Age::Assigned(UnicodeVersion { major: 1, minor: 1, micro: 0 })); assert_eq!(Age::of('\u{A0000}'), Age::Unassigned); assert_eq!( Age::of('\u{10FFFF}'), Age::Assigned(UnicodeVersion { major: 2, minor: 0, micro: 0 }) ); if let Some(uni_ver) = '🦊'.age().assigned() { assert_eq!(uni_ver.major, 9); assert_eq!(uni_ver.minor, 0); assert_eq!(uni_ver.micro, 0); } // Bidi let text = concat![ "א", "ב", "ג", "a", "b", "c", ]; assert!(!text.has_bidi_explicit()); assert!(text.has_rtl()); assert!(text.has_ltr()); assert_eq!(text.chars().nth(0).unwrap().bidi_class(), BidiClass::RightToLeft); assert!(!text.chars().nth(0).unwrap().is_ltr()); assert!(text.chars().nth(0).unwrap().is_rtl()); assert_eq!(text.chars().nth(3).unwrap().bidi_class(), BidiClass::LeftToRight); assert!(text.chars().nth(3).unwrap().is_ltr()); assert!(!text.chars().nth(3).unwrap().is_rtl()); let bidi_info = BidiInfo::new(&text, None); assert_eq!(bidi_info.paragraphs.len(), 1); let para = &bidi_info.paragraphs[0]; assert_eq!(para.level.number(), 1); assert_eq!(para.level.is_rtl(), true); let line = para.range.clone(); let display = bidi_info.reorder_line(para, line); assert_eq!( display, concat![ "a", "b", "c", "ג", "ב", "א", ] ); // Normalization assert_eq!(compose('A', '\u{30a}'), Some('Å')); let s = "ÅΩ"; let c = s.nfc().collect::<String>(); assert_eq!(c, "ÅΩ"); }
