Main database adapter trait

This is the entry point for database operations. It provides:

• Connection management
• Factory methods for inspectors and runners
• Database-specific configuration

Each database type (PostgreSQL, MySQL, etc.) implements this trait.

Required Methods

fn inspector(&self) -> Box<dyn SchemaInspector>

Get a schema inspector for this database

The inspector is used for read-only schema introspection.

fn migration_runner(&self) -> Box<dyn MigrationRunner>

Get a migration runner for this database

The runner is used for executing schema changes.

fn database_type(&self) -> &str

Get the database type identifier

Returns a string like “postgresql”, “mysql”, “sqlite”, etc.

fn test_connection<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Test the database connection

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
