Example

#[macro_use]
extern crate hyperscan;

use hyperscan::*;

fn callback(id: u32, from: u64, to: u64, flags: u32, _: &BlockDatabase) -> u32 {
    assert_eq!(id, 0);
    assert_eq!(from, 5);
    assert_eq!(to, 9);
    assert_eq!(flags, 0);

    println!("found pattern #{} @ [{}, {})", id, from, to);

    0
}

fn main() {
    let pattern = &pattern!{"test", flags => HS_FLAG_CASELESS|HS_FLAG_SOM_LEFTMOST};
    let db: BlockDatabase = pattern.build().unwrap();
    let scratch = db.alloc().unwrap();

    db.scan::<BlockDatabase>("some test data", 0, &scratch, Some(callback), Some(&db)).unwrap();
}
