Contains v0.1.0
Reports whether a substring occurs anywhere in the string.
Package: Text
Signature
func Contains(self, needle: String) -> bool;
Parameters
| Name | Type | Description |
|---|---|---|
needle | String | The bytes to search for. |
Returns
true when the bytes of needle occur anywhere in the string. The empty needle is contained in every string, and a needle longer than the string is contained in none.
This is IndexOf with the offset thrown away, and it costs the same — ask IndexOf instead when the position matters.
Example
import Text::String;
func Main() -> int {
var text = String::From("Hello, Rux!");
var needle = String::From("Rux");
text.Contains(needle); // true
needle.Free();
text.Free();
return 0;
}
