serialisationBincode is a serializer implementation for Serde. If you stick a #[derive(Deserialize, Serialize)] on your struct, Bincode can efficiently serialize and deserialize those structs to and from bytes. Bincode is unique in that it’s a format that was built specifically for the Rust serialization ecosystem. Tight coupling with Serde allows Bincode to be very fast and serialize to very small payloads.
