Rust + SeaORM Database Explicit Contractsv1.0.0

A SaaS platform needs to manage multiple tenants with consistent database schemas. Using SeaORM entities as the single source of truth, the platform can automatically create and migrate tables for each tenant without manual DDL scripts, ensuring all tenants have identical structures.

An e-commerce system tracks orders through states like Draft, Active, and Archived. By defining status enums with can_transition_to checks, the system enforces valid transitions and prevents invalid state changes (e.g., Archived back to Draft). Entity files document all rules clearly.

A healthcare app stores patient data with strict schema requirements (e.g., non-nullable fields, JSON for flexible medical history). Using Entity First, the schema is auto-synced from code, and nullable fields use Option<T>. Soft-delete flag filters active records, ensuring compliance.

A fintech application handles monetary transactions requiring atomic cross-table operations. Transactions wrapped in SeaORM's `db.transaction` ensure rollback on failure. Enums for transaction type (e.g., Credit, Debit) with transition rules prevent invalid sequences.

A CMS uses JSON fields for flexible content structure, defined as strong types with FromJsonQueryResult. Entity files include file-level doc comments describing versioning logic (e.g., soft-delete and revision tracking). Queries always filter out deleted records.

Offer the Rust + SeaORM contract framework as an open-source project for developers. Generate revenue through paid enterprise support, consulting services, and custom integrations for large-scale projects.

Provide consulting services to teams migrating from legacy SQL patterns to SeaORM Entity First. Help refactor codebases to enforce explicit contracts, with automated CI checks via the provided detection script.

Build a platform that uses the contract rules to auto-generate Rust backend code for database schemas. Offer it as a middleware that syncs entity definitions to cloud databases, with a subscription model for hosting and scaling.
