详细描述

Transport-neutral backbone shared by every method-model client implementation.

This is an internal implementation header used by the public Client template; application code should depend on client.h instead. ClientImpl extends NodeImpl with the connectivity bookkeeping that lets a client wait for its counterpart server and issue blocking calls. Concrete transports such as DdsClientImpl or ShmClientImpl derive from this class and implement the pure virtual is_connected() and call() entry points.

ImplType: The constructor stamps impl_type with kClient. The base NodeImpl surfaces this value to discovery, bag, and proxy layers so they can route status callbacks correctly.

Role table

Concern	Owner in this hierarchy
Wire send / receive	Transport subclass (e.g. `DdsClientImpl`)
Connection detection	`ClientImpl` (helper condition variable)
Blocking call timing	`ClientImpl` + `AckManager` in subclass
Connect callback fan	`ClientImpl::detect_connected()`

Internal API contract

Method	Provided by	Notes
`is_connected() const`	Subclass override	Queries the live transport handle.
`call(req, cb, timeout)`	Subclass override	Performs the blocking round-trip.
`update_connected()`	This class	Invoked from discovery threads on state change.
`detect_connected(cb)`	This class	Stores the user callback and primes it.
`wait_for_connected(t)`	This class	Sleeps on the helper condition variable.
`interrupt()`	This class	Wakes waiters when the node is being shut down.

Internal Notes: is_resp_type captures whether the public Client template expects a response payload; backends that implement fire-and-forget RPC flavours may read it to skip the response wait.
