Schemerz

Schemerz is a database schema migration library for Rust that supports directed acyclic graph (DAG) dependencies between migrations. It currently has adapters for the following databases:

• PostgreSQL: schemerz-postgres
• SQLite: schemerz-rusqlite

Other Rust schema migration libraries to consider if you do not require DAG migration dependencies:

• schemamama (recommended -- this is the basis for Schemerz's API)
• dbmigrate
• migrant

Development

Version bumping (including changelog release section versioning) is handled by cargo-release, e.g.:

cargo release --workspace minor

Acknowledgements

Schemerz started as a fork of the schemer crate by Andrew Champion. The name "Schemerz" is a nod to its origin, as well as a play on the German word "Schmerz" meaning "pain" (which aptly describes database migrations).
