hors "how to parse json in rust" -a

- Answer from https://stackoverflow.com/questions/30292752/how-do-i-parse-a-json-file

Solved by the many helpful members of the Rust community:

extern crate rustc_serialize;
use rustc_serialize::json::Json;
use std::fs::File;
use std::io::Read;

fn main() {
    let mut file = File::open("text.json").unwrap();
    let mut data = String::new();
    file.read_to_string(&mut data).unwrap();

    let json = Json::from_str(&data).unwrap();
    println!("{}", json.find_path(&["Address", "Street"]).unwrap());
}

#[cfg(test)]
use mockiato::mockable;

#[cfg_attr(test, mockable)]
trait Greeter {
    fn greet(&self, name: &str) -> String;
}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn greet_the_world() {
        let mut greeter = GreeterMock::new();

        greeter
            .expect_greet(|arg| arg.partial_eq("world"))
            .returns(String::from("Hello world"));

        assert_eq!("Hello world", greeter.greet("world"));
    }
}
