Ractor is a pure-Rust actor framework inspired by Erlang's gen_server, providing actor message processing, supervision trees, and lifecycle management. It supports tokio and async-std runtimes, with a companion ractor_cluster library for distributed, cluster-based deployments.

Use cases

• build concurrent actor-based systems in Rust
• implement supervision trees for fault-tolerant services
• distribute actors across a cluster of nodes
• replace hand-rolled tokio message-passing with a structured actor model
• build Erlang-style gen_server patterns in Rust

When to choose

• you want an Erlang-inspired actor model with Rust performance
• you need supervision and lifecycle management for concurrent tasks
• you plan to scale to a distributed cluster of actors

When to avoid

• you need a simple thread pool rather than an actor model
• your project is not Rust-based
• you require a battle-tested framework with a very large ecosystem
