Crate fraiseql_db 

fraiseql-db

Database abstraction layer for FraiseQL v2.

This crate provides database-agnostic access to multiple database backends:

• PostgreSQL (primary, full feature set)
• SQL Server (enterprise)

It also provides the shared DB-level types used by the compilation and execution layers: SQL hint types and extended filter operators.
