Hi Alistair,

Thanks for your patch.

It looks like the cargo patch does not apply correctly. Is this working
on your side on the master branch?

ERROR: cargo-native-1.92.0-r0 do_patch: Applying patch '/srv/pokybuild/yocto-worker/genericx86-64/build/layers/openembedded-core/meta/recipes-devtools/rust/files/0001-bootstrap-Ensure-host-documentation-is-built-before-.patch' on target directory '/srv/pokybuild/yocto-worker/genericx86-64/build/build/tmp/work/x86_64-linux/cargo-native/1.92.0/sources/rustc-1.92.0-src/src/tools/cargo'

Perhaps you used the wrong -p or --strip option?

Can you have a look at this issue?
