Unexpected compiler error when comiling kube-rs docs on nightly

[jmintb]

I do not have a minimal example :(

When compiling the docs for kube-rs, I get the error outlined below. The command used is:

RUSTDOCFLAGS="--cfg docsrs" cargo +nightly doc --lib --workspace --features=derive,ws,oauth,jsonpatch,client,derive,runtime,admission,k8s-openapi/v1_26 --open

I believe I am hitting the same issue as mentioned here: kube-rs/kube#1150

Edit: included the stack tract with RUST_BACKTRACE=full

Code

no code :(

[Noratrieb]

probably a duplicate of #108334

[clux]

The line that broke in kube seems to be a combination of a doc comment with an inline re-export:

/// Re-exports from [`kube_core`](kube_core)
#[doc(inline)]
pub use kube_core as core;

in https://github.com/kube-rs/kube/blob/825aba81e124e4d5a3220ec2f33f64241021f49f/kube/src/lib.rs#L178-L180

changing the doc comment as noted in kube-rs/kube#1150 (comment) seems to avoid the error locally on latest nightly.

[petrochenkov]

Looks like this is not a duplicate of #108334 and is not fixed by #109266.

[petrochenkov]

Found the reason and fixed this locally, will submit the fix soon.

[petrochenkov]

Fixed in #109312.
