The record

Purpose: Refinery is a SQL migration toolkit for Rust that runs migrations on a provided database connection.
Run modes: Migrations can be embedded in Rust code or run through the refinery_cli command-line tool.
Migration formats: Migrations can be SQL files or Rust modules with a migration function that returns a String.
Supported drivers: The README lists postgres, tokio-postgres, mysql, mysql_async, rusqlite, and tiberius as supported drivers.
SQLx: The README says SQLx can be used by providing a Config that implements Migrate.
Migration tracking: Refinery records applied migration versions and metadata, then checks for divergent or missing migrations before executing unapplied ones.
Transactions: By default, each migration runs in its own transaction; grouped mode can wrap all migrations in one transaction.
Embedded migrations: The project can bake migrations into a binary so no additional files are needed when deployed.
Rollback: To undo a migration, users must create a new migration and write the changes that reverse it.
Version limit: Migration versions default to signed 32-bit integers; the int8-versions feature enables 64-bit versions and must be enabled before use on a database.
Additional drivers: The maintainers say limited bandwidth favors maintaining additional database drivers in external repositories; the README names Klickhouse as an example.
Rust support: The project aims to support stable Rust, the previous Rust version, and nightly.
License: The project is licensed under the MIT License.
Source availability: The project is published as a public GitHub repository.
Price from: Free
