IsSpace v0.1.0
Reports whether a byte is whitespace.
Package: Text
Signature
func IsSpace(ch: char8) -> bool;
Parameters
| Name | Type | Description |
|---|---|---|
ch | char8 | The byte to test. |
Returns
true for space (' '), tab ('\t'), newline ('\n'), and carriage return ('\r'), and false for every other byte. These four are exactly the bytes String::Trim removes.
The test is on one byte, so it says nothing about the whitespace characters that UTF-8 encodes in more than one — a non-breaking space is not whitespace here.
Example
import Text::IsSpace;
func Main() -> int {
IsSpace(c8' '); // true
IsSpace(c8'\n'); // true
IsSpace(c8'a'); // false
return 0;
}
