rust-gravatar is a small Rust library that generates Gravatar image URLs based
on the
official Gravatar specification.
```rust extern crate gravatar; use gravatar::{Gravatar, Rating};
let url = Gravatar::new("email@example.com") .setsize(Some(150)) .setrating(Some(Rating::Pg)) .imageurl(); asserteq!( url.as_str(), "https://secure.gravatar.com/avatar/5658ffccee7f0ebfda2b226238b1eb6e?s=150&r=pg" ); ```
