Server::run abruptly returns when a response payload is too large about coap-rs

[jasta]

I've got the block support working but realized that it might be better to merge the lower level part I built into coap-lite instead, then a separate smaller PR here to integrate it automatically. See martindisch/coap-lite#21

The RFC 7959 was mentioned before. But the pr still not be finished. It seems the author no longer active. You can check if it could help you.

Awesome thanks for the pointer, I'll take a look and see if this can be done cleanly on the latest codebase.

Unfortunately after trying pretty hard to make this and Observe support integration work I've decided I need to go a different direction and start a new project with a higher level API goal for cleaner integration: https://github.com/jasta/coap-server-rs. While coap-rs has been extremely useful in getting me started there are some pretty significant architectural challenges that would need to be overcome for good generic support for more advanced features and that would end up taking the project in a very different direction with potentially a lot of disruption to current users. For now I'm choosing to incubate a more experimental but convenient approach in the linked repo above (which does have transparent Observe and Block-wise support)
