Sim Transport

transport: sim — simulation transport for testing; mirrors channel semantics without real sockets.

address syntax: sim:<inner-addr> (wraps a concrete inner transport address)

dial / serve:

• ChannelAddr::Sim(inner)

• sim::dial::<M>(inner: ChannelAddr) -> NetTx<M>

• sim::serve::<M>(inner: ChannelAddr).await -> (ChannelAddr, NetRx<M>)

notes:

• Used only in tests and simulations.

• Wraps an underlying concrete transport (e.g., local, tcp) to mimic end-to-end semantics without real network I/O.
