This crate ships async + no_std + no-alloc implementations of various network protocols.

Suitable for microcontrollers and embedded systems in general.

• HTTP client and server
• Websocket send/receive
• DNS Captive Portal
• mDNS responder
• DHCP cient and server
• Raw IP & UDP packet send/receive (useful in combination with the DHCP client and server)
• MQTT client (currently just a slim wrapper around rumqttc, so needs STD)
• TCP, UDP and raw sockets

• The Rust Standard library
• The networking stack of Embassy
• Any other platform, as long as you implement (a subset of) edge-nal
  • The necessary minimum being the Read / Write traits from embedded_io_async - for modeling TCP sockets - and UdpReceive / UdpSend from edge-nal - for modeling UDP sockets
  • Most crates (edge-captive, edge-dhcp, edge-ws, edge-raw) also provide a compute-only subset that does not need embedded-io-async or edge-nal traits

PRs welcome!
