Function icu::plurals::rules::parse

pub fn parse(input: &[u8]) -> Result<Rule, ParserError>

Unicode Plural Rule parser converts an input string into a Rule AST.

A single Rule contains a Condition and optionally a set of Samples.

A Condition can be then used by the resolver to test against PluralOperands, to find the appropriate PluralCategory.

Samples are useful for tooling to help translators understand examples of numbers covered by the given Rule.

At runtime, only the Condition is used and for that, consider using parse_condition.

Examples

use icu_plurals::rules::parse;

let input = b"i = 0 or n = 1 @integer 0, 1 @decimal 0.0~1.0, 0.00~0.04";
assert_eq!(parse(input).is_ok(), true);
