MarsSeed [1] filed a deletion request for parallel-rust [2]: Proposal to delete this alternative implementation from 2017 of repo's 'parallel'. The latter comes from GNU. The GitHub repository has been archived. [a] While the description there points to a rewrite of this tool, but that is for Redox OS, a purely Rust-based, Unix-like microkernel operatin system. Also, there seems to be no interest here in either this old parallel- rust or in the new redox-parallel.
