Contains

Reports whether a substring occurs anywhere in the string.

Module: 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;

var text = String::From("Hello, Rux!");
var needle = String::From("Rux");

text.Contains(needle); // true

needle.Free();
text.Free();
