something like:

```rust
rpc!{
match message {
    icd::Ident(time_ms) => handle_ident(outie, whbody.wh.seq_no, time_ms, &mut led).await,
    icd::Uptime(()) => handle_uptime(outie, whbody.wh.seq_no).await,
    icd::ResetToBootloader(()) => handle_reset_bootload(outie, whbody.wh.seq_no).await,
    NO_MATCHING_KEY => {},
    GOOD_KEY_BAD_DECODE => {},
}
}
```

or something
