Module schema 

Schema definition and registration system.

This module provides types for defining database schemas declaratively in Rust. Schemas are registered at compile time via proc macros and used for:

• TypeScript client generation
• Migration diffing
• Runtime introspection

Key Types

• TableDef - Table schema with fields and indexes
• FieldDef - Column definition with Rust and SQL types
• FunctionDef - Query/mutation signatures for codegen
• SchemaRegistry - Global registry populated by macros

Example

#[derive(sqlx::FromRow, Serialize, Deserialize)]
#[forge::model]
pub struct User {
    pub id: Uuid,
    pub email: String,
    pub created_at: DateTime<Utc>,
}

Structs

EnumDef

Enum type definition.

EnumVariant

Enum variant definition.

FieldDef

Definition of a model field.

FunctionArg

Function argument definition.

FunctionDef

Function definition.

IndexDef

Single-column index definition.

SchemaRegistry

Global registry of all schema definitions. This is populated at compile time by the proc macros. Uses BTreeMap for deterministic iteration order.

TableDef

Complete table definition.

Enums

FunctionKind

Function kind (query, mutation, job, cron, workflow).

RelationType

Relation type for foreign key relationships.

RustType

Rust type information for code generation.

SqlType

PostgreSQL column types.

Traits

ModelMeta

Trait implemented by all FORGE models. Generated by the #[forge::model] macro.
