prost-msg-build

build prost struct with msg id so as to realize type judgment

• examples

message Fail{
   enum MsgId {  None=0;Id = 150002; }
   int64 number=1;
   string message=2;
}

auto impl MsgId and const fn

    #[prost(int64, tag = "1")]
    pub number: i64,
    #[prost(string, tag = "2")]

about prost-build

prost-build

prost-build makes it easy to generate Rust code from .proto files as part of a Cargo build. See the crate documentation for examples of how to integrate prost-build into a Cargo project.

protoc

prost-build uses protoc to parse the proto files. There are two ways to make protoc available for prost-build:

• Include protoc in your PATH. This can be done by following the protoc install instructions.
• Pass the PROTOC=<my/path/to/protoc> environment variable with the path to protoc.
