Greetings,
I am trying to package a rust application and the build fails. I am not sure
how to debug that. When I try to compile the application using `cargo install',
it does pass and build just fine. However, when I try to build the application
(imported using the cargo importer) using `guix build', I get this error:
Compiling tonic v0.10.2
error[E0277]: the `?` operator can only be used in an async block that
returns `Result` or `Option` (or another type that implements `FromResidual`)
-->
/tmp/guix-build-netavark-1.10.3.drv-0/netavark-1.10.3/guix-vendor/rust-tonic-0.10.2.tar.gz/src/transport/server/incoming.rs:32:45

28 | / async_stream::try_stream! {
29 | | tokio::pin!(incoming);

32 | | yield item.map(ServerIo::new_io)?
| | ^ cannot use the `?`
operator in an async block that returns `()`
33 | | }
34 | | }
| |_____- this function should return `Result` or `Option` to accept `?`
|
= help: the trait `FromResidual<std::result::Result<Infallible, IE>>` is
not implemented for `()`
For more information about this error, try `rustc --explain E0277`.
error: could not compile `tonic` (lib) due to previous error
I am not know rust, but this looks like a code error? If that is the case, I do
not understand why `cargo install' works, since it should be using the same
code.
Could someone nudge me in the right direction regarding how to debug this issue?
I am not really sure where to start.
Thank you and have a nice day,
Tomas Volf
