safer-ffi-gen 0.9.2 failed to build

[stefunctional]

Crate name

safer-ffi-gen

Build failure link

https://docs.rs/crate/safer-ffi-gen/0.9.2/builds/943834

Additional details

safer-ffi-gen 0.9.1 was built and documented successfully by docs.rs. 0.9.2 is identical to 0.9.1 modulo the difference in the patch version number.

The failure appears to be due to the dependency safer-ffi 0.1.3 failing to build. However docs.rs was able to build and document this crate successfully.

I was not able to reproduce the failure locally running cargo doc.

Looking at the Cargo.toml for safer-ffi, they are using the docs.rs metadata and a special feature for the docs build.

You probably have to do the same.

Thank you for your answer. Unless I misunderstood, that does not explain why safer-ffi-gen 0.9.1 built successfully. The only change in safer-ffi-gen 0.9.2 is literally a version bump:

Both depend on safer-ffi = "0.1.3" and that is the version that was used to build based on the logs and Cargo.lock in docs.rs.

[Nemo157]

There was a new API added to std recently causing that error: https://doc.rust-lang.org/nightly/std/macro.cfg_match.html

rust-lang/rust#117057 is somewhat related, but about it being in the prelude, it looks like safer-ffi is doing a manual glob-import which runs into the same problem and probably needs another upstream issue.

[stefunctional]

Thank you @Nemo157! That seems to be the cause indeed and safer-ffi has already published a new version where the macro was renamed. The docs for safer-ffi-gen should be built successfully the next time it is published.
