Enum SchemaMigrationExecutionOutcome 

pub enum SchemaMigrationExecutionOutcome {
    AlreadyApplied,
    Executed(MigrationRunOutcome),
}

SchemaMigrationExecutionOutcome

SchemaMigrationExecutionOutcome reports whether schema evolution skipped an already-applied migration or delegated a planned migration to db::migration. The lower migration outcome is preserved unchanged when execution occurs.

Variants

AlreadyApplied

Executed(MigrationRunOutcome)

Implementations

impl SchemaMigrationExecutionOutcome

pub const fn already_applied(self) -> bool

Return whether schema evolution skipped execution because the registry already contains this migration id/version.

pub const fn migration_outcome(self) -> Option<MigrationRunOutcome>

Return the lower migration-run outcome when execution occurred.
