Crate yauth_migration 

Declarative schema system and migration file generator for yauth.

This crate has zero ORM dependencies — it is a pure code generator. It provides:

• Schema types (TableDef, ColumnDef, ColumnType, etc.)
• Core + plugin schema definitions
• Schema collector with topological sort by FK dependencies
• Dialect-specific DDL generators (Postgres, SQLite, MySQL)
• Schema diff engine for incremental migrations
• Migration file generators (diesel up.sql/down.sql, sqlx numbered .sql)
• yauth.toml config file support
• Schema hash for tracking

Modules

config

yauth.toml configuration file support.

diff

Schema diff engine.

generate

Migration file generators for diesel and sqlx.

plugin_schemas

Schema definitions for each built-in plugin.

Structs

ColumnDef

Definition of a single column.

ForeignKey

Foreign key reference from a column to another table’s column.

IndexDef

Index definition for a table.

TableDef

Definition of a single table.

YAuthSchema

Merged schema: all tables topologically sorted by FK dependencies.

Enums

ColumnType

Abstract column type – each dialect maps this to a concrete SQL type.

Dialect

Supported SQL dialects for DDL generation.

OnDelete

ON DELETE action for foreign keys.

Orm

Supported ORM formats for migration file generation.

SchemaError

Error during schema collection.

Constants

ALL_PLUGINS

All known plugin names.

Functions

collect_schema

Collect and merge core + plugin schemas, then topologically sort by FK deps.

collect_schema_for_plugins

Collect a schema from a list of plugin names plus core tables.

core_schema

Returns the core yauth tables: users, sessions, audit_log.

generate_ddl

Generate DDL for a schema in the given dialect.

generate_diesel_schema

Generate diesel table! macro definitions as Rust source text.

generate_mysql_ddl

Generate complete MySQL DDL for the entire schema.

generate_mysql_drop

Generate DROP TABLE IF EXISTS statement for a single table (MySQL).

generate_mysql_drops

Generate DROP TABLE statements for a list of tables in reverse order (MySQL).

generate_postgres_ddl

Generate complete Postgres DDL for the entire schema.

generate_postgres_drop

Generate a DROP TABLE IF EXISTS statement for a single table.

generate_postgres_drops

Generate DROP TABLE statements for a list of tables in reverse order.

generate_sqlite_ddl

Generate complete SQLite DDL for the entire schema.

generate_sqlite_drop

Generate DROP TABLE IF EXISTS statement for a single table (SQLite).

generate_sqlite_drops

Generate DROP TABLE statements for a list of tables in reverse order (SQLite).

is_known_plugin

Check if a plugin name is valid (even if it has no database tables). Plugins like admin, status, telemetry, and openapi are code-only.

plugin_schema_by_name

Get the schema tables for a plugin by name.

schema_hash

Compute a deterministic hash of the schema for tracking purposes.
