Support for SQLite's JSON/JSONB has landed on diesel

Hello there!

I'm proud to announce one of my first major public contribution to the Rust ecosystem.

My PR to add support for SQLite's JSON/JSONB in diesel, the safe, extensible ORM and Query Builder for Rust, has just been merged on \master\\.

Here is a concrete example of what used to be available to the PostgreSQL backend only, but is now supported on SQLite too:

table! {
    contacts {
        id -> Integer,
        name -> Text,
        address -> Jsonb,
    }
}

let santas_address: serde_json::Value = serde_json::from_str(r#"{
    "street": "Article Circle Expressway 1",
    "city": "North Pole",
    "postcode": "99705",
    "state": "Alaska"
}"#)?;
let inserted_address = insert_into(contacts)
    .values((name.eq("Claus"), address.eq(&santas_address)))
    .returning(address)
    .get_result::<serde_json::Value>(connection)?;
assert_eq!(santas_address, inserted_address);
