memable

An embeddable durable execution engine for Rust.

Unlike platforms such as Temporal or Restate, memable is a library — it runs inside your process with zero external dependencies. Workflows recover via key-based memoisation rather than positional replay, so you can deploy new code, fix bugs, and selectively re-execute steps without breaking in-flight workflows.

Target domains

• Data integration & sync pipelines — reliable multistep ETL with automatic retry and checkpointing.
• AI agentic workflows — durable orchestration of LLM calls, tool use, and branching agent logic.

Status

Early development — the public API is not yet stable.

Minimum Supported Rust Version

The MSRV is 1.85 (Rust 2024 edition).
