Tower is a Rust library of modular, reusable components for building robust networking clients and servers around a request/response Service abstraction. It provides protocol-agnostic middleware such as timeouts, rate limiting, retries, load balancing, and load shedding via composable Service and Layer traits.
Use cases
- add timeouts and retries to async request handling in Rust
- implement rate limiting or load shedding for a network service
- build composable middleware for Rust HTTP servers and clients
- load balance requests across multiple backend services
- model clients and servers with a unified async request/response trait
When to choose
- you are building Rust networking clients or servers with a request/response pattern
- you want reusable, protocol-agnostic middleware like timeout, retry, or rate limiting
- you use tokio or another async runtime and want composable service layers
When to avoid
- your protocol is entirely stream-based rather than request/response
- you need a no_std-compatible core (use tower-layer and tower-service instead)
- you want a full web framework rather than a service abstraction library
