Trait for executing migration plans

The executor coordinates between the planner, migration runner, and other components to safely execute migrations.

Required Methods

fn execute<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, tenant: &'life1 TenantContext, plan: &'life2 MigrationPlan, runner: &'life3 dyn MigrationRunner, ) -> Pin<Box<dyn Future<Output = Result<ExecutionResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Execute a migration plan for a tenant

Arguments

• tenant - The tenant context
• plan - The migration plan to execute
• runner - The migration runner to use

Returns

Execution result with success status and details.

fn dry_run<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, tenant: &'life1 TenantContext, plan: &'life2 MigrationPlan, runner: &'life3 dyn MigrationRunner, ) -> Pin<Box<dyn Future<Output = Result<ExecutionResult>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Execute a migration plan in dry-run mode

This validates the plan and returns what would happen, but doesn’t actually execute any changes.

Dyn Compatibility

This trait is dyn compatible.

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