If you're just patching in later versions of the crates, this should work:
SRC_URI += "crate://crates.io/<target>/<version>"
EXTRA_OECARGO_PATHS = "${CARGO_VENDORING_DIRECTORY}/<target>-<version>"
or if you have them patched in a git repo:
SRC_URI += "git://.../<target>"
EXTRA_OECARGO_PATHS = "${WORKDIR}/<target>"
Only works if they're already in crates.io though
(https://doc.rust-lang.org/cargo/reference/overriding-dependencies.html)
and you'll probably run into

I suspect we really need some standard machinery here.
