Crate cur 

cur - Your unicode pattern hunting companion.

This module provides a Cur, which can determine if a pattern known as an Odor matches a unicode string known as the “search”. Odors can “mark” any number of parts of their pattern with [Name]s. For each match that a Cur finds, it can return a [Catch] that has location information known as a Find for each of the marks of the Odor.

Examples

use cur::*;

// Define an Odor.
odor!(HELLO_WORLD = ["Hello ", .. as name, '!']);

// Create a Cur that will hunt for the Odor.
let mut cur = Cur::new(&HELLO_WORLD);

// Set the search to be hunted.
cur.set_search("Hello Bob!");

// Execute the hunt by requesting information from the Cur.
assert!(!cur.is_clear());

// The Cur iterates on the Catch found.
if let Some(catch) = cur.next() {
    assert_eq!(catch.get("name").map(Find::as_str), Some("Bob"));
} else {
    panic!("Cur did not find catch");
}
