Build: could not find `iterator` in `signal_hook` and SIGUSR1 not found in scope

[vostrnad]

Which command failed? cargo build --locked --release (with or without --no-default-features)

What was the error message?

Thanks for reporting this issue, and sorry for the delayed response! Does this issue reproduces on latest master?

[vostrnad]

Yes, the error message appears exactly the same.

I guess it's related to https://docs.rs/signal-hook/latest/signal_hook/iterator/index.html not being supported on Windows.

Maybe we can try to use https://crates.io/crates/ctrlc (which seems to support Windows).
