Crate premix_core 

Premix ORM Core

Core definitions and traits for the Premix ORM ecosystem. Provides the Model trait, Executor abstraction, and QueryBuilder.

Architecture

• Model: The core trait that all database entities must implement.
• Executor: Abstracts over connection pools and transactions.
• QueryBuilder: A type-safe SQL query generator with support for:
  • Filtering (eq, ne, gt, lt, in)
  • Pagination (limit, offset)
  • Relations (eager loading)
  • Soft Deletes

This crate is designed to be used with premix-macros for compile-time SQL generation overrides.
