note: i believe that if we switched the workspace to use resolver = "2", we wouldn't have to cd into each crate's directory. but, this only works on Rust 1.51+, so we would have to wait until our MSRV is 1.51 (e.g., we can't make that change today).

it might be worth leaving a TODO comment for that, though...

oh, another thought. while we're changing this, we may want to change this to use the github actions working-directory key, rather than (cd tracing-subscriber && ...). this is what the cargo hack checks already do:

tracing/.github/workflows/CI.yml

Line 72 in 005b97a

working-directory: ${{ matrix.subcrate }}

Suggested change
run: (cd tracing-subscriber && cargo test --lib --tests --no-default-features)
run: cargo test --lib --tests --no-default-features
working-directory: tracing-subscriber

We may want to change the other runs in this CI job as well. However, we can also do this in a separate branch.
