-fst
-===
-This crate provides a fast implementation of ordered sets and maps using finite
-state machines. In particular, it makes use of finite state transducers to map
-keys to values as the machine is executed. Using finite state machines as data
-structures enables us to store keys in a compact format that is also easily
-searchable. For example, this crate levages memory maps to make range queries,
-regular expression queries and Levenshtein (edit) distance queries very fast.

-### Documentation
-
-[Full API documentation and examples.](http://burntsushi.net/rustdoc/fst/)
-
-
-### Installation
-
-Simply add a corresponding entry to your `Cargo.toml` dependency list:
-
-```ignore
-[dependencies]
-fst = "0.1"
-```
-
-And add this to your crate root:
-
-```ignore
-extern crate fst;
-```
-
-
-### Example
-
-This example demonstrates building a set in memory and executing a fuzzy query
-against it. Check out the documentation for a lot more examples!
-
-```rust
-use fst::{IntoStreamer, Streamer, Levenshtein, Set};
-
-// A convenient way to create sets in memory.
-let keys = vec!["fa", "fo", "fob", "focus", "foo", "food", "foul"];
-let set = try!(Set::from_iter(keys));
-
-// Build our fuzzy query.
-let lev = try!(Levenshtein::new("foo", 1));
-
-// Apply our fuzzy query to the set we built.
-let mut stream = set.search(lev).into_stream();
-
-let keys = try!(stream.into_strs());
-assert_eq!(keys, vec!["fo", "fob", "foo", "food"]);
