[Qustion] How can i use null for graphql

[liangyuanpeng]

In my case, i need to use null for graphql, some like :

stargazers(first: 1,after: null) {
...
}

I tried the way

query.graphql

query RepoView($owner: String!, $name: String!,$startFirst: Int,$after:Option) {
...
}

main.rs

let q = RepoView::build_query(repo_view::Variables {
        owner: owner.to_string(),
        name: name.to_string(),
        start_first: starFirst,
        after: Option::None,
    });

I just got the err and i just started using rust, how can i do for it ?!

Thanks any help!

Let's try with this.

let q = RepoView::build_query(repo_view::Variables {
        owner: owner.to_string(),
        name: name.to_string(),
        start_first: starFirst,
        after: None,
    });

Piggy-backing on this question, but it's related: Is there an easy way to model the implicit vs explicit null in a query, like https://graphql-rust.github.io/juniper/master/advanced/implicit_and_explicit_null.html ?

Basically, I'd like to be able to at will omit certain fields from the query. I guess I could do that with @include, but that's a bit ugly (requires an extra boolean argument for each optional field). Could we have something like juniper's Nullable?
