Project Mentat is a persistent, embedded relational knowledge base written in Rust, inspired by Datomic and DataScript. It offers a flexible schema model with change listeners, designed for embedding in applications like Firefox and mobile platforms.
Use cases
- embed a flexible relational store in a Rust application
- model evolving domain schemas without raw SQL
- store structured facts with Datomic-style schema attributes
- build mobile apps needing an embedded knowledge base
- listen to data changes outside the database layer
When to choose
- you want a Datomic/DataScript-like embedded store in Rust
- you need flexible, evolvable schemas rather than fixed SQL tables
- you're forking and maintaining it yourself
When to avoid
- you need a maintained, production-supported database
- you need key-value or document storage
- you require active community support or recent updates
