/*!
A crate for string searching. The main trait is `Searcher`, which has a function for finding fixed
things in long byte-strings. Currently, the only implementer of `Searcher` is `TwoWaySearcher`.

# Example

```rust
use memmem::{Searcher, TwoWaySearcher};
let search = TwoWaySearcher::new("dog".as_bytes());
assert_eq!(search.search_in("The quick brown fox jumped over the lazy dog.".as_bytes()), Some(41));
```
*/

#[cfg(test)]
extern crate quickcheck;

mod two_way;

pub use two_way::TwoWaySearcher;

/// A trait that searches for patterns in byte-strings.
pub trait Searcher {
    /// Search for something in a byte-string. Returns the starting index of the match, if found.
    fn search_in(&self, haystack: &[u8]) -> Option<usize>;
}
