This is a basic demonstration of how to write an ICMP (‘ping’) server using a NIF in about 100 lines of elixir and 100 lines of Zig.
This might be able to be deployed as a ‘real’ library. Would anyone be interested in using this? I am very happy to put more work into making this a quality release (modulo zig itself being still experimental) if people are interested, as there really isn’t a satisfactory ICMP solution in the BEAM (and the :socket library maintainers have suggested that ICMP is not going to happen)
