toad-msg

Low-level representation of CoAP messages.

The most notable item in toad_msg is Message; a CoAP message very close to the actual byte layout.

Allocation

CoAP messages are growable and dynamically sized:

  • The message payload (http equiv: the request/response body)
  • the number of options (http equiv: headers)
  • the value of an option (http equiv: header value)

Performance

This crate uses criterion to measure performance of the heaped & heapless implementations in this crate as well as coap_lite::Packet.

In general, toad_msg::VecMessage performs identically to coap_lite (+/- 5%), and both are much faster than toad_msg::ArrayVecMessage.
