Brilliant! may I suggest addition of cd bolt-sidecar && cargo hack check --all-features
Crate

Hey @0ex-d thanks for the suggestion, I tried looking into what benefits cargo hack has over regular cargo check, but it's a bit unclear. What do you like about it?

I use cargo hack check --feature-powerset. It does a thing of mixing various features and testing this scenerios.
More like:

cargo check --features "json keystore-tests"
cargo check --no-default-features
cargo check --all-features
...
