Crate audb 

AuDB - Application Database Compiler

AuDB is a compile-time framework that transforms database queries and schemas into optimized, type-safe Rust applications with embedded databases.

Core Concepts

• Gold Files (.au): Universal container format for queries, schemas, and config
• Compile-Time: All parsing, validation, and optimization at build time
• Multi-Language: Support HyperQL, SQL, Cypher, and more
• Type-Safe: Compile-time type checking for queries and data
• Single Binary: Database + queries + server in one executable

Usage

use audb::Project;

// Load all gold files from a directory
let project = Project::from_directory("./gold")?;

// Validate the project
project.validate()?;

// Generate Rust code (typically done in build.rs)
let code = project.generate_code()?;

Module Organization

• parser: Gold file parser (.au format)
• model: Project model (schemas, queries, config)
• schema: Schema system supporting multiple formats
• validation: Compile-time validation and type checking
• project: Project management and file discovery
