5# Multimap implementation for Rust
6
7This is a multimap implementation for Rust. Implemented as a thin wrapper around
8std::collections::HashMap.
9
10## Example
11
12````rust
13extern crate multimap;
14
15use multimap::MultiMap;
16
17fn main () {
18 let mut map = MultiMap::new();
19
20 map.insert("key1", 42);
21 map.insert("key1", 1337);
22 map.insert("key2", 2332);
23
24 assert_eq!(map["key1"], 42);
25 assert_eq!(map.get("key1"), Some(&42));
26 assert_eq!(map.get_vec("key1"), Some(&vec![42, 1337]));
27}
28````
