Struct `IdStart`

struct IdStart

Characters that can begin an identifier.

If using NFKC to fold differences between characters, use XidStart instead. See Unicode Standard Annex #31 for more details.

Example

use icu::properties::CodePointSetData;
use icu::properties::props::IdStart;

let id_start = CodePointSetData::new::<IdStart>();

assert!(id_start.contains('x'));
assert!(!id_start.contains('1'));
assert!(!id_start.contains('_'));
assert!(id_start.contains('ߝ'));  // U+07DD NKO LETTER FA
assert!(!id_start.contains('ⓧ'));  // U+24E7 CIRCLED LATIN SMALL LETTER X
assert!(id_start.contains('\u{FC5E}'));  // ARABIC LIGATURE SHADDA WITH DAMMATAN ISOLATED FORM
