Struct coap_handler_implementations::TypeHandler

pub struct TypeHandler<H, S: TypeSerializer = SerdeCBORSerialization>where
    H: TypeRenderable,{ /* private fields */ }

Wrapper for resource handlers that are implemented in terms of GETting, POSTing or PUTting objects in CBOR format.

The wrapper handles all encoding and decoding, options processing (ignoring the critical Uri-Path option under the assumption that that has been already processed by an underlying request router), the corresponding errors and block-wise GETs.

More complex handlers (eg. implementing additional representations, or processing query aprameters into additional data available to the TypeRenderable) can be built by forwarding to this (where any critical but already processed options would need to be masked from the message’s option) or taking inspiration from it.
