Volo is a high-performance, strongly extensible RPC framework written in Rust for building microservices. It provides Thrift, gRPC, and HTTP implementations, IDL-driven code generation, and a middleware abstraction powered by AFIT and RPITIT.

Use cases

• build microservices in rust with rpc
• serve and call thrift rpc services
• build grpc servers and clients in rust
• generate rust code from thrift and protobuf idl
• build high-performance http services in rust
• bootstrap a new rust rpc project from the command line

When to choose

• you are building microservices in Rust and want a mature RPC framework
• you need Thrift or gRPC support with IDL-based code generation
• performance and low allocation overhead are priorities
• you want an extensible middleware abstraction

When to avoid

• your stack is not Rust
• you need a simple REST-only service with minimal framework overhead
• you rely on an ecosystem of RPC features available only in Go or Java frameworks
