Hi.
pm215 pointed me at this, as I have some background in Rust.
I definitely approve of having Rust in Qemu. I don't have an opinion
about whether the sources should be vendored this way.
But, I tried to build this, and
error: failed to select a version for the requirement `cc = "=1.0.70"`
candidate versions found which didn't match: 1.0.69
location searched: directory source
`/volatile/rustcargo/Rustup/Qemu/qemu.pwt/rust/vendored` (which is replacing
registry `crates-io`)
required by package `nix v0.20.1`
... which is depended on by `qga v0.1.0
(/volatile/rustcargo/Rustup/Qemu/qemu.pwt/qga)`
perhaps a crate was updated and forgotten to be re-vendored?
As a reminder, you're using offline mode (--offline) which can sometimes
cause surprising resolution failures, if this error is too confusing you may
wish to retry without the offline flag.
I think the most important part here is to get the general APIs,
presented to general Rust code in Qemu, right. So I wanted to review
those via the output from rustdoc.
I tried commenting out the `replace-with` in .cargo/config.toml
but evidently the systme isn't intended to be used that way.
