StartsWith v0.1.0
Reports whether the string opens with a prefix.
Package: Text
Signature
func StartsWith(self, prefix: String) -> bool;
Parameters
| Name | Type | Description |
|---|---|---|
prefix | String | The bytes to look for at the front. |
Returns
true when the string's first bytes are the bytes of prefix. Every string starts with the empty one, and none starts with a prefix longer than itself.
The comparison is byte for byte and case-sensitive, on the same terms as Equals.
Example
import Text::String;
func Main() -> int {
var path = String::From("/usr/local/bin");
var root = String::From("/usr");
path.StartsWith(root); // true
path.StartsWith(String::New()); // true -- the empty prefix always matches
root.Free();
path.Free();
return 0;
