Tonic is a Rust implementation of gRPC over HTTP/2, providing async/await client and server support built on hyper and tokio, with prost-based codegen from protobuf definitions. It is designed as a high-performance, interoperable core building block for production Rust systems.

Use cases

• build a gRPC server in Rust
• create a gRPC client from protobuf definitions
• implement bidirectional streaming RPCs
• add TLS-secured gRPC services
• generate Rust client/server code from .proto files
• build microservices communicating over gRPC
• add load balancing and health checking to gRPC channels

When to choose

• you need native gRPC in Rust with first-class async/await support
• you want high-performance HTTP/2 RPC between Rust services
• you need protobuf-based codegen for clients and servers
• you require streaming, TLS, load balancing, or custom metadata in gRPC
• you want an interoperable gRPC implementation that works with other language stacks

When to avoid

• you need a simple REST or JSON API rather than gRPC
• your project does not use async Rust or the tokio ecosystem
• you need gRPC-Web support in the browser directly
• you want a C-binding-based gRPC implementation matching the official grpc core exactly
