Implementations§

Source§

impl ReUtil

Source

pub fn is_match(re: &str, text: &str) -> bool

检查文本是否匹配给定的正则表达式模式

§参数
  • re - 正则表达式模式字符串
  • text - 要检查的文本字符串
§返回值

如果文本匹配正则表达式模式则返回true,否则返回false

§Panics

当正则表达式模式无效时会panic

Source

pub fn find_first<'a>(re: &str, text: &'a str) -> Option<&'a str>

在给定文本中查找第一个匹配正则表达式的子串

§参数
  • re - 要匹配的正则表达式字符串
  • text - 要搜索的文本内容
§返回值

返回第一个匹配的子串引用,如果没有匹配则返回None

§示例
let result = find_first(r"\d+", "abc123def456");
assert_eq!(result, Some("123"));
Source

pub fn find_all(re: &str, text: &str) -> Vec<String>

在给定文本中查找所有匹配正则表达式的子串

§参数
  • re - 要使用的正则表达式字符串
  • text - 要搜索的文本
§返回值

返回包含所有匹配子串的字符串向量

§示例
let matches = find_all(r"\d+", "abc123def456");
assert_eq!(matches, vec!["123", "456"]);
