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