rust-libp2p build breaks on master's update

[laurentsenta]

the worfklow started to fail in go-libp2p, here is an example of a run:

We need to investigate, my first intuition:

Now that we merged: #37
We are using "latest" release and not master.

We expect that when rust release a new version and updates master, that won't break other tests (because we only test releases known by libp2p/test-plans).

BUT we do use a master definition in the Cargo file, this is how we deal with multiple versions:

test-plans/ping/rust/Cargo.toml

Line 27 in 520162a

libp2pv0480 = {package = "libp2p", git = "https://github.com/libp2p/rust-libp2p", branch = "master", default_features = false, features = [ "websocket", "mplex", "yamux", "tcp-async-io", "ping", "noise", "dns-async-std" ], version = "0.48.0", optional = true}

That line will break if the package is bumped to version 0.49 because it will try to load the repo and won't find the 0.48 version.

We might need to drop this line and use a rewrite in the master group.

We might need to drop this line and use a rewrite in the master group.

Off the top of my head, this sounds reasonable to me.

Thanks for the input @mxinden,
this should get the CI back to green, that's my current priority,
