ferro-deployments 0.2.53

//! `CreateDeploymentsTable` + `CreateDeploymentPointersTable` —
//! SeaORM migrations creating the `deployments` and `deployment_pointers`
//! tables. Portable across SQLite + Postgres: no backend-specific SQL,
//! only the SchemaManager DDL builder.
//!
//! Consumers register both in their own `Migrator` in order:
//! ```rust,ignore
//! impl MigratorTrait for Migrator {
//!     fn migrations() -> Vec<Box<dyn MigrationTrait>> {
//!         vec![
//!             Box::new(ferro_deployments::CreateDeploymentsTable),
//!             Box::new(ferro_deployments::CreateDeploymentPointersTable),
//!             // ... your app migrations
//!         ]
//!     }
//! }
//! ```
