Is there a way to dynamically add an observable resource, say after the server is started?

Would be nice to support functions with dynamic arguments based on generics being built up in a chain of function calls

Tokio should not be required to use this project and in particular we want to target embassy and possibly even simpler runtimes that support no_std.

Would be really nice to be able to run integration tests against the gold standard libcoap to ensure correctness and interoperability

While trying to pass some query parameters via URI, I noticed that e.g. resource '/abc', doesn't match if the URI contains query part '?.....'. So, the '/abc?a=1' is not matched at '/abc'.

Glancing over standard didn't provide me with definite answer, if this should be supported or not so I checked libcoap source, and there in coap uri parsing source (lines 233-260) they do split path into uri-path and uri-query parts.

Can this be implemented?

Tracking issue for the first big round of features that are needed for this project to be useful to others. Incomplete items in this list block crates.io submission

Features:

• Working Observe support
• Block-wise transfer
• Multicast UDP
• TCP transport (mostly as a proof of concept to show abstractions are correct)
• /.well-known/core query filtering

Maturity:

• rustdoc all the things

If a request is taking a long time to process we should send back an Acknowledgement message then later the regular Response message when it's ready.
