[PULL 036/153] rust: move strict lints handling to meson.build

Posted by Paolo Bonzini 1 week, 4 days ago

Simplify rustc_args.py, and align its code with what Meson's own Cargo.toml
translator does in v1.10.

Bump unknown_lints to "forbid", so that it will certainly override Cargo.toml's
"allow" level.
