Exclude instantiations from statistics?

[jaskij]

A few of the structs in my code #[derive(valuable::Valuable)] from valuable. Those derives show up on the report as not-covered, which is fine, but I would like to exclude them from the statistics. Or the whole report, either way is fine.

Is this something that is achievable and I'm just missing it, or is not currently supported?

With the current Rust coverage mechanism, this needs to be handled on the derive macro side.

Perhaps we need to stabilize the #[coverage(off)] attribute first.

See also rust-lang/rust#84605 (comment) and subsequent 3 comments.

Considering rust-lang/rust#120185, I think using #[automatically_derived] in valueable-derive resolves this issue.

Filed tokio-rs/valuable#136 to do it.
