unicode-brackets

提供确定字符是否为开闭括号以及更改这些字符方向的方法。

此crate使用的定义来自Unicode双向算法(UAX #9)。具体请参阅文件http://www.unicode.org/Public/UCD/latest/ucd/BidiBrackets.txt

此crate使用no_std属性，消除了对std的依赖。

extern crate unicode_brackets;
use unicode_brackets::UnicodeBrackets;

fn main() {
    /// Some of the many different kinds of opening bracket.
    let opening_chars = ['(', '[', '⦑'];

    for c in opening_chars {
        assert!(c.is_open_bracket());
    }

    let closing_chars: Vec<char> = opening_chars.iter()
                                                .map(|c| c.to_close_bracket())
                                                .collect();
    assert_eq!(closing_chars[..], [')', ']', '⦒']);
