futures_util version needs to be 0.3.17 as a minimum

[chipsenkbeil]

Expected Behavior

I can compile async-graphql version 4.0.1.

Actual Behavior

Steps to Reproduce the Problem

It looks like you have an import of futures_util::Stream instead of futures_util::stream::Stream here: https://github.com/async-graphql/async-graphql/blob/master/src/types/merged_object.rs#L6

The top-level re-export doesn't become available until futures_util 0.3.17. If you're supporting older versions, then I think this needs to be refactored! :)

Other details

It looks like there's a nightly feature of cargo that can be used to update the lock file to the. minimal versions of dependencies as defined in Cargo.toml so you can guarantee that your project compiles and tests successfully with those versions. I think it also impacts other crates, so may be a bit difficult to use.

cargo +nightly -Z minimal-versions update
cargo test --all --all-features
