Decide whether to transition all examples from make test to cargo test

[mdinger]

All the examples could be transitioned to cargo test from make test as discussed on PR #433 (comment) . Currently this would be awkward without toml-lang/toml#235 and so we're waiting for that to materialize before a decision is made for or against transitioning.

@steveklabnik I'm assuming postponing this is fine for now. If so, can you flag this postponed?

[steveklabnik]

yes, I want everyone to go to cargo test, but haven't had the time to do
the work. I personally don't care if the compact toml syntax lands or not.

[steveklabnik]

(there is no postponed tag)

[mdinger]

Okay. That's helpful because previously I'd be hesitant to start porting because I wasn't sure if it'd be accepted.

I want the syntax so I doubt I'll work on porting it until then but someone else is welcome to it if they want

[mdinger]

rust-lang/cargo#1225 is wip to provide dependency access for cargo. If this supports export to JSON, it could potentially allow a direct migration without many changes aside from the Cargo.toml and the structure file.

[steveklabnik]

The changes to toml have landed.

This is now mdbook test 👍
