Episode 9 – gRPC with Lucio Franco.

A deep dive into the world of asynchronous networking in Rust with Lucio Franco, maintainer of Tonic, Tower, Tokio, and Hyper. We explore the origins and design of gRPC and its Rust implementation, Tonic—how it came to be, what problems it solves, and why it matters. Along the way, Lucio shares insights into open source collaboration, Google’s work on gRPC for Rust, and what the future might hold for the broader async Rust ecosystem.
