emitbrown

This project is a fork of RustyEmitter and it uses hashbrown to replace std::collections::HashMap.

usage

```rust extern crate emitbrown; extern crate hashbrown;

use emitbrown::{Events, Emitter}; use hashbrown::HashMap;

fn main(){
let (mut emitter, callback) = ( // create a new emitter instance Emitter::new(),

    // creating the handler in the same lifetime 
    &mut |data:& mut HashMap<String, String>| { 
        println!("IT WORKS!");
        for (key, value) in data {
            println!("{}: {}", key, value);
        }
    }
);

// listen to the "IT WORKS" event
emitter.on("IT WORKS".to_string(), callback);

// fire the "IT WORKS" event with an empty HashMap;
emitter.emit("IT WORKS".to_string(), &mut HashMap::new());

// fire it again passing some more data
let mut data : HashMap<String, String> = HashMap::new();

data.insert("some data".to_string(), "here".to_string());
emitter.emit("IT WORKS".to_string(), &mut data);

} ```
