Contents of the free form package.metadata section

extern crate serde_json;
#[macro_use]
extern crate serde_derive;

#[derive(Debug, Deserialize)]
struct SomePackageMetadata {
    some_value: i32,
}

fn main() {
    let value = json!({
        "some_value": 42,
    });

    let package_metadata: SomePackageMetadata = serde_json::from_value(value).unwrap();
    assert_eq!(package_metadata.some_value, 42);
}
