Expand description
Lightweight, embedded migration runner for SQL-backed session services.
This module provides shared types and free functions that track applied schema versions in a per-backend registry table and execute only unapplied forward-only migration steps.
The types (MigrationStep, AppliedMigration, MigrationError) are
always compiled. The SQL runner functions ([run_sql_migrations],
[sql_schema_version]) require the sqlite or postgres feature.
Structsยง

Migration - Record of an applied migration stored in the registry table.
