This crate provides some base definitions for the PLDM messaging specification (DMTF DSP0240).
Communication with remote endpoints is through the MCTP base crate's
mctp::ReqChannel and mctp::Listener traits.
Platform-specific implementations of traits
are passed to the pldm transfer functions (pldm_xfer, pldm_rx_req,
pldm_tx_resp, pldm_rx_resp and _borrowed equivalents).
