Crate twg_proto_bundle 

Bundle a protobuf source into the artefacts the descriptor toolkit and an operator need: one combined FileDescriptorSet (.pb), one proto3 file per package, and a fully-qualified message-type manifest. See ADR-0063 and docs/blueprints/proto-bundle-implementation-plan.md.

The source may be a single .proto, a bare directory of protos, or a Java/Maven/Gradle repo with many src/main/proto roots — all resolved through one entry point. Compilation is pure Rust via protox (no protoc on PATH).

use std::path::Path;
use twg_proto_bundle::{bundle, BundleOptions};

let out = bundle(Path::new("/path/to/proto-source"), Path::new("./out"), &BundleOptions::default())?;
// out.messages.roots contains e.g. "com.example.orders.Order"
std::fs::write("./out/bundle.pb", &out.descriptor_set).unwrap();

Structs

Bundle

The in-memory result of bundling, returned regardless of what was written.

BundleOptions

Which artefacts to write to the output directory. All default on.

MessageManifest

The message-type inventory written to <name>.messages.json.

MissingImport

One unresolved import and the staged files that require it.

RenderedProto

One rendered proto3 file.

Enums

BundleError

Anything that can go wrong resolving, deduping, compiling, or rendering a proto source into a bundle.

OnConflict

How to treat an import path that resolves to differing content under different include roots.

WktImports

Where the Google well-known-type imports live.

Functions

bundle

Resolve, compile, and render source, writing the opts.emit subset to out_dir and returning the full Bundle.
