Implementation of a count map in Rust. A map that holds a counter as a value, that gets incremented each time the key is added to the map. This implementation simply decorates the HashMap from the Rust std library.
Add the following to your Cargo.toml:
toml
[dependencies]
countmap = "0.1"
Next, add this to your crate root:
rust
extern crate countmap;
Now you can use a count map in your code:
rust
fn main() {
let map = countmap::CountMap::new();
map.insert_or_increment("foo");
}
