pub fn frame_rpc_message(body: &[u8]) -> Vec<u8> ⓘExpand description
Prepend a TCP record mark to an XDR body.
Sets the last-fragment bit (MSB) and encodes the payload length in
the lower 31 bits. Standalone callers (e.g. super::client::probe_server_alive)
use this when they cannot go through super::client::NfsCompoundClient::rpc_call.
