[feat] Old version of Cargo fails silently

[TomByrne]

Describe the problem

I'm new to Tauri and was attempting to run the template (yarn + react).
Because I was running an older version of Cargo, the build failed, but because the rust build output gets replaced by the yarn build, the issue wasn't easy to work out.

Describe the solution you'd like

Ideally, if the 'edition' in Cargo.toml is too new, the yarn build wouldn't get run, so that you could see the error in the output.

What do you mean with gets replaced by the yarn build? Can you give us an example?

[TomByrne]

I'm on Windows, in vscode (so a Powershell console), and immediately after this issue happens, the yarn/react build starts, which clears the cargo build output, including the error message. If I kill the build at just the right time I can read the message, but it's like a 0.3s window or something.

So this is the important output that gets cleared:

error: failed to parse manifest at `C:\_projects\Lab\storage-view\src-tauri\Cargo.toml`

Caused by:
  failed to parse the `edition` key

Caused by:
  this version of Cargo is older than the `2021` edition, and only supports `2015` and `2018` editions.

And this is what replaces it:

Note that the development build is not optimized.
To create a production build, use yarn build.

Thanks for the report. Also you should update your Rust :)
