aerro

aerro is an early-stage Rust library for cross-service gRPC errors.

The goal is to provide a complete error framework for service-oriented Rust systems using tonic, prost, and the broader gRPC ecosystem:

• full call traces across service boundaries
• typed error upcasting and downcasting
• efficient transport through gRPC status metadata and protobuf details
• low overhead abstractions suitable for high-throughput services
• compatibility with established Rust error tooling where it is a good fit

This first release reserves the crate name while the public API is designed.

Status

The crate is not ready for production use yet.
