Why libc crate is green?

[ozkriff]

Because it uses "unsafe" only inside macros?

Good find, thank you! Needs investigation.

The scanning needs to expand macros to detect this case. Can cargo and rustc be used to output the expanded code?

Looks like macro expansion requires nightly, source: https://crates.io/crates/cargo-expand

#52 makes libc and similar unsafe usage present as "?" and with the default terminal foreground color. See the changelog for 0.6.0 in the readme.
