rust-query

Ergonomic API to write composable and nested relational queries

The 'rust-query' library provides an API for the Rust programming language, to work with SQLite databases and build composable database queries with confidence. While the library already has many innovative features, it still lacks some of the essential features that are required for most applications. That is why this project adds support for booleans and datetimes in the schema (using check-constraints), more SQL operators, and custom non-unique indices. We will also improve developer experience with a guide, better error messages, and support for using rust-query with existing migration systems.
