This directory contains a manual test to check whether the micro_rpc crate can
be depended on from a crate in another workspace.
See project-oak#4573 for context.
This crate overwrites the WORKSPACE_ROOT env variable with an invalid value in
the .cargo/config.toml file, which is necessary to shadow the corresponding
one in the root of this repository, to simulate an external workspace that would
not have that env variable set.
To reproduce the issue, run the following command from the repository root:
env --chdir=./micro_rpc_workspace_test bash -c 'cargo clean && cargo test'If the issue is present, this will error out with something like
process didn't exit successfully: `/home/tzn/src/oak/micro_rpc_workspace_test/target/debug/build/micro_rpc-e60764e369835bbd/build-script-build` (exit status: 101)
