wildcard

wildcard is a rust crate for wildcard matching.

Here's how to use it:

let wildcard = Wildcard::new("*foo?*bar".as_bytes()).unwrap();

assert!(wildcard.is_match("fooofooobar".as_bytes()));

Special characters can be escaped to represent their literal symbol:

let wildcard = Wildcard::new(r"\*\?".as_bytes()).unwrap();

assert!(!wildcard.is_match("ab".as_bytes()));
assert!(wildcard.is_match("*?".as_bytes()));

You can also capture the substring that matched the metasymbols of the wildcard:

let wildcard = Wildcard::new("* is a * style?".as_bytes()).unwrap();

let captures: Vec<&[u8]> = wildcard.captures("Lambic is a beer style!".as_bytes()).unwrap();

assert_eq!(captures, ["Lambic".as_bytes(), "beer".as_bytes(), "!".as_bytes()]);

String matching

For performance reasons wildcard does not match directly on strings, but it supports matching on slices of chars:

let p = "*foo?*bar".chars().collect::<Vec<_>>();
let wildcard = Wildcard::new(&p).unwrap();

assert!(wildcard.is_match(&"fooofooobar".chars().collect::<Vec<_>>()));

Matching customization

With wildcard you can configure these properties of a wildcard:

1. Configure the symbols for the metasymbols * and ? as well as the escape symbol.
2. Support for the metasymbol ? can be disabled.
3. Support for escaping can be disabled.
4. Support for case-insensitive matching.
