Expand description
This crate simplifies writing build scripts (build.rs) for Exonum and Exonum services.
Since Protobuf is the Exonum default serialization format, build.rs is mostly used
to compile Protobuf files and generate a corresponding code. This code is used later by
the Exonum core and services.
In order to use the crate, call ProtobufGenerator with the required params.
See ProtobufGenerator docs for an example.
§File Sets
There are several predefined sets of Protobuf sources available for use, split according
to the crate the sources are defined in. These sets are described by ProtoSources:
- Crypto sources: cryptographic types used in services and the code.
- Common sources: types that can be used by various parts of Exonum.
- MerkleDB sources: types representing proofs of existence of element in database.
- Core sources: types used in core and in system services such as supervisor.
| File path | Set | Description |
|---|---|---|
exonum/crypto/types.proto | Crypto | Basic types: Hash, PublicKey and Signature |
exonum/common/bit_vec.proto | Common | Protobuf mapping for BitVec |
exonum/proof/list_proof.proto | MerkleDB | ListProof and related helpers |
exonum/proof/map_proof.proto | MerkleDB | MapProof and related helpers |
exonum/blockchain.proto | Core | Basic core types (e.g., Block) |
exonum/key_value_sequence.proto | Core | Key-value sequence used to store additional headers in Block |
exonum/messages.proto | Core | Base types for Ed25519-authenticated messages |
exonum/proofs.proto | Core | Block and index proofs |
exonum/runtime/auth.proto | Core | Authorization-related types |
exonum/runtime/base.proto | Core | Basic runtime types (e.g., artifact ID) |
exonum/runtime/errors.proto | Core | Execution errors |
exonum/runtime/lifecycle.proto | Core | Advanced types used in service lifecycle |
Each file is placed in the Protobuf package matching its path, similar to well-known Protobuf
types. For example, exonum/runtime/auth.proto types are in the exonum.runtime package.
