Function LastIndexAny 

pub fn LastIndexAny(s: impl AsRef<[byte]>, chars: impl AsRef<str>) -> int

LastIndexAny interprets s as a sequence of UTF-8-encoded Unicode code points. It returns the byte index of the last occurrence in s of any of the Unicode code points in chars. It returns -1 if chars is empty or if there is no code point in common.

zh-cn

字符串chars中的任一utf-8字符在s中最后一次出现的位置，如不存在或者chars为空字符串则返回-1。

Example

use gostd_bytes as bytes;

assert_eq!(4,bytes::LastIndexAny("go gopher", "go"));
assert_eq!(8,bytes::LastIndexAny("go gopher", "ordent"));
assert_eq!(-1,bytes::LastIndexAny("go gopher", "fail"));
assert_eq!(4,bytes::LastIndexAny("go gopher".as_bytes(), "go"));
assert_eq!(8,bytes::LastIndexAny("go gopher".as_bytes(), "ordent"));
assert_eq!(-1,bytes::LastIndexAny("go gopher".as_bytes(), "fail"));
