impl StrUtil

Source

pub fn split<'a>(str: &'a str, delimiter: &str) -> Vec<&'a str>

将字符串按照指定分隔符进行分割

§参数
  • str - 需要分割的字符串切片
  • delimiter - 用作分割依据的分隔符字符串
§返回值

返回一个包含分割后子字符串的向量,每个元素都是原字符串的切片引用

§示例
let result = split("hello,world,rust", ",");
assert_eq!(result, vec!["hello", "world", "rust"]);
Source

pub fn remove_prefix(str: &str, prefix: &str) -> String

从字符串中移除指定的前缀

如果字符串以指定前缀开头,则返回移除前缀后的字符串; 否则返回原字符串的副本。

§参数
  • str - 需要处理的原始字符串
  • prefix - 要移除的前缀字符串
§返回值

返回移除前缀后的字符串,如果不需要移除前缀则返回原字符串的副本

Source

pub fn remove_suffix(str: &str, suffix: &str) -> String

从字符串中移除指定的后缀

如果字符串以指定后缀结尾,则返回移除该后缀后的字符串; 否则返回原字符串的副本。

§参数
  • str - 需要处理的原始字符串
  • suffix - 要移除的后缀字符串
§返回值

返回处理后的字符串。如果原字符串以指定后缀结尾,则返回移除后缀后的字符串; 否则返回原字符串的副本。

Source

pub fn reverse(str: &str) -> String
