IsSpace

Reports whether a byte is whitespace.

Module: 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;

IsSpace(c8' ');  // true
IsSpace(c8'\n'); // true
IsSpace(c8'a');  // false
