ICE when documenting embedded-io with nightly: node HirId(...) cannot be placed in TypeckResults #149089
Description
I receive an ICE trying to build the nightly docs for the embedded-io library.
Reproduction Steps
git clone https://github.com/rust-embedded/embedded-hal.git
cd embedded-hal/embedded-io
RUSTDOCFLAGS="--cfg docsrs --generate-link-to-definition -Z unstable-options" cargo +nightly doc
Expected Outcome
Docs build.
Actual Output
❯ RUSTDOCFLAGS="--cfg docsrs --generate-link-to-definition -Z unstable-options" cargo +nightly doc
