A crate for accessing VK API in Rust (synchronously).

# Usage
Add the dependency to your `Cargo.toml` file:

```toml
[dependencies]
rvk = "0.2"
```

Also, add this line to your crate:

```rust
extern crate rvk;
```

Now you can take a look at this crate's [API documentation](https://docs.rs/rvk) to learn more about the available functions.

# Example

```rust
extern crate rvk;
use rvk::{methods::*, APIClient, Params};

extern crate serde;
#[macro_use]
extern crate serde_derive;
extern crate serde_json;
use serde_json::from_value;

#[derive(Deserialize)]
struct User {
    id: u64,
    first_name: String,
    last_name: String,
}

fn main() {
    let api = APIClient::new("your_access_token"); // Create an API Client

    let mut params = Params::new(); // Create a HashMap to store parameters
    params.insert("user_ids", "1");

    let res = users::get(&api, params);

    match res {
        Ok(v) => { // v is `serde_json::Value`
            let users: Vec<User> = from_value(v).unwrap();
            let user = &users[0];

            println!(
                "User #{} is {} {}.",
                user.id, user.first_name, user.last_name
            );
        }
        Err(e) => println!("{}", e),
    };
}
```
