Module normalize 

Name normalization for SQL statements using the visitor pattern.

This module provides a flexible framework for transforming object names in SQL statements. It uses a trait-based visitor pattern to support different normalization strategies while sharing the same traversal logic.

Normalization Strategies

• Fully Qualifying: Transforms names to database.schema.object format
• Flattening: Transforms names to database_schema_object format (single identifier)

Usage

use mz_deploy::project::resolve::normalize::NormalizingVisitor;

// Create a fully qualifying visitor
let visitor = NormalizingVisitor::fully_qualifying(&fqn);

// Or create a flattening visitor
let visitor = NormalizingVisitor::flattening(&fqn);

Module Structure

• transformers: Name transformation strategies (FullyQualifying, Flattening, Staging)
• visitor: The NormalizingVisitor that traverses SQL AST and applies transformations
• mod_rewriter: AST-based rewriting of database/schema names in mod statements
