Async + no_std + no-alloc implementation of IP and UDP packet creation and parsing.
The edge_raw::io module contains implementations of the edge_nal::RawBind trait, as well as of the edge_nal::RawReceive and edge_nal::RawSend traits.
These are useful in the context of protocols like DHCP, which - while working on top of UDP - need to be capable of receiving and sending packets to peers that do not have an IP address assigned yet.
For other protocols, look at the edge-net aggregator crate documentation.
Look at the edge-dhcp crate as to how to utilize the capabilities of edge-raw.
