`rust-gravatar` is a small Rust library that generates Gravatar image URLs based
on the
[official Gravatar specification](http://en.gravatar.com/site/implement/images/).

## Example

```rust
extern crate gravatar;
use gravatar::{Gravatar, Rating};

let url = Gravatar::new("email@example.com")
    .set_size(Some(150))
    .set_rating(Some(Rating::Pg))
    .image_url();
assert_eq!(
    url.as_str(),
    "https://secure.gravatar.com/avatar/5658ffccee7f0ebfda2b226238b1eb6e?s=150&r=pg"
);
```
