rustHow to match whitespace with a regex in Rust?
Matching whitespace with a regex in Rust is done using the \s
character class. This character class matches any whitespace character, including spaces, tabs, and newlines.
let whitespace_regex = Regex::new(r"\s").unwrap();
let whitespace_string = "This string has whitespace!";
assert!(whitespace_regex.is_match(whitespace_string));
The code above will assert that the whitespace_regex
matches the whitespace_string
.
