In this episode, we sit down with Daniel Wagner-Hall, a maintainer of Rules Rust and a Bazel expert, to explore how Bazel and Rust work together to streamline builds and cross-compilation.

Daniel shares insights from his extensive experience, including his role in open-sourcing Bazel at Google and his consulting work helping teams optimize their Bazel-Rust integrations.

We dive into the nuances of using Bazel with Rust’s package manager, Cargo, and the trade-offs between maintaining Cargo compatibility and fully embracing Bazel-first workflows.

Daniel explains how Rust developers can keep their builds smooth using Bazel, and what to watch out for when integrating third-party dependencies like C libraries.

We also touch on IDE integration, cross-compilation, and the exciting future of Rust support in the gRPC ecosystem.

Whether you're new to Rust or a seasoned Bazel user, you'll find practical tips on how to make these powerful tools work together seamlessly.
