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
