kwap_msg

Low-level representation of CoAP messages.

alloc vs no_alloc

kwap_msg implements CoAP messages as either backed by:

• alloc: dynamically growable heap-allocated buffers
• no_alloc: static stack-allocated buffers

alloc::Message can be much easier to use and performs comparably to no_alloc, however it does require: std or a global allocator

Performance

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

In general, kwap_msg::alloc::Message is faster than coap_lite, which is much faster than no_alloc::Message.
