3. Our Starting Point
We had a Rust crate (dc-gossip) with:
- A UDP socket implementation
- Ping/Pong structs that could be serialized/deserialized
- A CrdsValue and CrdsData type definition
- A ContactInfo struct
- A Protocol enum with encode/decode methods
When we first ran it:
Ping sent... Pong received! ✓
PullRequest sent... ... ... nothing. ✗
Zero bytes came back after the PullRequest. The entrypoint was silently ignoring us. For weeks.
