Build-time integration for buffa.

Use this crate in your build.rs to compile .proto files into Rust code at build time. Parses .proto files into a FileDescriptorSet (via protoc or buf), then uses buffa-codegen to generate Rust source.

Example

// build.rs
fn main() {
    buffa_build::Config::new()
        .files(&["proto/my_service.proto"])
        .includes(&["proto/"])
        .compile()
        .unwrap();
}

Requirements

By default, requires protoc on the system PATH (or set via the PROTOC environment variable) — the same as prost-build and tonic-build.

If protoc is unavailable or outdated on your platform, buf can be used instead — see [Config::use_buf()]. Alternatively, feed a pre-compiled descriptor set via [Config::descriptor_set()].
