英文:
Differences between strings.Contains and strings.ContainsAny in Golang
问题
在源代码中：
<!-- language: go -->
// Contains返回true，如果substr在s中。
func Contains(s, substr string) bool {
return Index(s, substr) >= 0
}
// ContainsAny返回true，如果chars中的任何Unicode代码点在s中。
func ContainsAny(s, chars string) bool {
return IndexAny(s, chars) >= 0
}
唯一的区别似乎是substr和chars中的Unicode代码点。我编写了一些测试来测试它们两个。它们的行为似乎是相同的。我不明白何时使用哪个。
英文:
In the source code:
<!-- language: go -->
// Contains returns true if substr is within s.
func Contains(s, substr string) bool {
return Index(s, substr) >= 0
}
// ContainsAny returns true if any Unicode code points in chars are within s.
func ContainsAny(s, chars string) bool {
return IndexAny(s, chars) >= 0
}
the only difference seems to be substr and the Unicode code points in chars. I wrote some test to test both of them. Their behaviors seem to be identical. I don't understand when to use which.

我认为这两个函数完全不同。Contains函数用于检测一个字符串是否包含子字符串。ContainsAny函数用于检测一个字符串是否包含提供的字符串中的任何字符。
英文:
I think two functions are totally different. Contains are used to detect if a string contains a substring. ContainsAny are used to detect if a string contains any chars in the provided string.

Contains函数用于判断一个子字符串是否在字符串中。而ContainsAny函数用于判断字符串中是否包含任何Unicode字符。请查看文档。
func main() {
fmt.Println(strings.Contains("seafood", "aes"))
fmt.Println(strings.ContainsAny("seafood", "aes"))
fmt.Println(strings.Contains("iiii", "ui"))
fmt.Println(strings.ContainsAny("iiii", "ui"))
}
输出结果为：
false
true
false
true
英文:
Contains function reports whether a sub-string is within the string. Whereas ContainsAny function reports whether any Unicode code points in chars are within the string. Look at the documentation.
func main() {
fmt.Println(strings.Contains("seafood", "aes"))
fmt.Println(strings.ContainsAny("seafood", "aes"))
fmt.Println(strings.Contains("iiii", "ui"))
fmt.Println(strings.ContainsAny("iiii", "ui"))
}
The output is;
false
true
false
true
