tarpc is an RPC framework for Rust focused on ease of use, letting you define services directly in code without a separate schema language like protobuf. It supports pluggable transports, cascading cancellation, deadline propagation, and distributed tracing via OpenTelemetry.

Use cases

• build microservices in Rust with typed RPC
• replace gRPC with a pure-Rust, no-proto RPC framework
• call functions on a remote process over a pluggable transport
• propagate request deadlines across service call chains
• add distributed tracing to Rust service-to-service calls
• cancel in-flight remote requests by dropping the client call

When to choose

• you want RPC schemas defined in Rust code with no separate IDL compilation step
• you need cascading cancellation and deadline propagation across services
• your stack is Rust on both client and server and you want minimal boilerplate
• you need a pluggable transport rather than being locked to HTTP/2

When to avoid

• you need cross-language clients/servers (e.g., browser or Python callers) where protobuf-based gRPC fits better
• you require a mature ecosystem of gateways and tooling built around gRPC
• you need a stable 1.0 API - tarpc is still pre-1.0
