invalid message field Data.id

[makorne]

Thank you for the example project.
It is working!!!

But using it in real project with latest rusttc 1.53.0 (53cb7b09b 2021-06-17 makes a strangle issue:

syntax = "proto3";
package main_data;
import "rust.proto";

message Data {
    // generates the Uuid type instead of the string type
    string id = 1 [(rust.codegen).type = UUID];
}

Generates code:

#[derive(Clone, PartialEq, ::prost::Message)]
pub struct Data {
    /// generates the Uuid type instead of the string type
    #[prost(uuid, tag="1")]
    pub id: ::uuid::Uuid,
}

But then follows a build error:

error: proc-macro derive panicked

#[derive(Clone, PartialEq, ::prost::Message)]
  |                            ^^^^^^^^^^^^^^^^
  |
  = help: message: called `Result::unwrap()` on an `Err` value: invalid message field Data.id
          
          Caused by:
              no type attribute

Now I add to project as in example :

prost = "0.8"
url = "2"
uuid = "0.8"

[patch.crates-io]
prost = { git = 'https://github.com/kaiserkarel/prosit' }
prost-derive = { git = 'https://github.com/kaiserkarel/prosit' }
prost-types = { git = 'https://github.com/kaiserkarel/prosit' }
prost-build = { git = 'https://github.com/kaiserkarel/prosit' }

May be I should use something like:

#[macro_use]
pub extern crate prost_derive;

What do you think about this issue?
Any ideas?

Could you check what version of prost-build is used in the build.rs? And does the example compile for you? To me it seems like the correct prost-build handled the proto, but regular prost is used in the derive.

Your example compiled and the generated types work in his main {}.

But if the generated types are used in elementary workspace project - emerges this problem.
Please take a look.
I created test workspace here: https://github.com/makorne/prosit_workspace_test.git
