| # How to get a compatible version of protoc |
| |
| The protoc binary that you use to generate code needs to have a version that |
| exactly matches the version of the protobuf crate you are using. More |
| specifically, if you are using Rust protobuf `x.y.z` then you need to use protoc |
| `y.z`. See [here](https://protobuf.dev/support/version-support/) for more |
| details on our versioning scheme. |
| |
| The easiest way to get ahold of protoc is to download a prebuilt binary from the |
| matching release [here](https://github.com/protocolbuffers/protobuf/releases). |
| Just make sure protoc is on your `$PATH` when you run `cargo`. |
