Would it be possible to update socket2 to version 0.3.16+ (such as version 0.3.19)? Since rust-lang/rust#78802 landed in Rust 1.64, earlier versions of socket2 no longer build.

I took a stab at doing so:

cargo update -p socket2

but couldn't figure out how to run an older version of crate2nix to regenerate Cargo.nix. This failure is being observed in the staging-next branch of nixpkgs (c.f. NixOS/nixpkgs#193494), which has Rust updated.
