Is it really absolutely necessary to have this in the top level
directory of the source tree?

These seem to be relevant:

https://stackoverflow.com/questions/46786956/can-i-add-a-dependent-crate-that-is-a-subdirectory-in-a-git-repository

which refers to:

https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html

It seems like cargo should pick up the Cargo.toml file from
plugins/rust automatically?

As a meta-comment, it's easier to review patches sent inline, one patch 
per email, rather than multiple patches as opaque attachments to one 
email; the difference being that I can immediately reply to the patch in 
my mailer without having to open a file and pasting contents.  git 
send-email makes it easy to send patch series in this way, if you want 
to figure out how to set that up.  But it's not a showstopper if you 
keep your current workflow for submitting patches.

Turns out it isn't.  It didn't work when I tried it the first time, and
I
thought that this was the reason why.  But it turns out the real reason was
because you had been generating your Cargo.toml file with autotools.
That's no longer the case, after my last patch.  So you don't need the
workspace Cargo.toml file after all.
