Struct embedded_nal_coap::CoAPShared

pub struct CoAPShared<const CONCURRENT_REQUESTS: usize> { /* private fields */ }

The shared state of a CoAP main loop, which would typically run as a server and client simultaneously.

This is usually created once and then [.split()] up into a client and a server part.

Relevant generics:

• CONCURRENT_REQUESTS indicates how many requests may be outstanding simultaneously on the client side. Note that this distinct from NSTART in two ways: NSTART is counted per peer (this is total), and is decremented as soon as the request is ACK’ed (this is until the (final) response has been processed).

Implementations

impl<const CONCURRENT_REQUESTS: usize> CoAPShared<CONCURRENT_REQUESTS>

pub fn new() -> Self

pub fn split<'a>( &'a self ) -> (CoAPRuntimeClient<'a, CONCURRENT_REQUESTS>, CoAPRunner<'a, CONCURRENT_REQUESTS>)

Split a CoAPShared into a client and a server/runner part.

While technically both of them are just thin wrappers around a shared reference, this split ensures that the otherwise-panicking constraints about who grabs which mutices when are upheld.
