Tonic Rust

Use these conventions for Rust gRPC clients and servers built with hyperium/tonic.

Source Baseline

• Prefer released docs from docs.rs/tonic, crates.io, and the matching release branch.
• Treat GitHub master carefully: tonic notes that master is preparing breaking changes. For released code, check the v0.14.x branch.
• Current docs.rs baseline checked for this skill: tonic 0.14.6, tonic-prost-build 0.14.6, MSRV 1.88.
• Tonic is gRPC over HTTP/2 built on Tokio, Hyper, Tower, and Prost.
• For protobuf compilation through Prost, use tonic-prost-build; tonic-build now points users to tonic-prost-build for .proto compilation.

Cargo

Use pinned compatible crate families. Start narrow and add features intentionally.
