# derec-proto
Generated Rust protobuf types for the DeRec protocol.
This crate contains the Rust structures generated from the DeRec `.proto`
schema files using `prost`.
These types represent the wire-level protocol messages exchanged by
DeRec participants.
This crate is primarily intended for:
- SDK developers
- low-level protocol integrations
- tooling that needs direct access to DeRec message structures
Most application developers should depend on `derec-library`,
which provides a higher-level API and complete protocol flows.
> [!INFO]
> The Rust types in this crate are generated from `.proto` schema files.
> Changes should be made in the schema definitions rather than editing the generated code directly.

## Example
```rust
use derec_proto::ContactMessage;
// Constructing a message directly (typically handled by derec-library)
let msg = ContactMessage::default();
```
> [!NOTE]
> In the current SDK design, applications should not construct or manipulate
> protobuf messages directly. Instead, use `derec-library`, which produces
> and consumes opaque `wire_bytes`.

## Relationship with other crates
The DeRec Rust implementation is composed of multiple crates:
- `derec-library` – main SDK used by applications
- `derec-cryptography` – internal cryptographic primitives
- `derec-proto` – generated protocol message types
Most developers should only interact with `derec-library`.
