Found this during PR review. We could leverage `#[serde(borrow)]` for zero-copy deserialization for messages from the compiler. We can't use `&str` fields because they may contain escape sequences in the future, which fails the deserialization. See serde-rs/json#742
`artifact` field is an (absolute) path to emitted artifact like /home/projects/foo/target/debug/deps/libbar-73d672db2af2c9a8.rmeta It is worth not copying them.
