4/// and removing non-alphanumeric characters.

6/// # Example
7///
8/// ```rust
9/// use ic_dbms_api::prelude::{SlugSanitizer, Value, Sanitize as _};
10///
11/// let value = Value::Text("  Hello,       World!  ".into());
12/// let sanitizer = SlugSanitizer;
13/// let sanitized_value = sanitizer.sanitize(value).unwrap();
14/// assert_eq!(sanitized_value, Value::Text("hello-world".into()));
15/// ```
