Interface implements interface

[Angusross111]

Does ariadne support interfaces implementing interfaces? This was merged into the spec in 2020 graphql/graphql-spec#373

I have tried to implement the Interface example in the docs with a slight modification here https://gist.github.com/Angusross111/a7fd5dec3156ebb678c6b26423fcb97b

Is this the correct way to create resolvers for it? and/or is it currently supported?

Looks like I wasnt implementing the spec correctly. Adding both interfaces to the type seems to have solved it:

type Order implements SearchResult & IdResult {
    ref: String!
    client: Client!
    summary: String!
    url: String!
    id: String!
}

type Product implements SearchResult & IdResult {
    name: String!
    sku: String!
    summary: String!
    url: String!
    id: String!
}
