Reference

Every module’s interface, generated by odoc from its .mli, where each function says what it does, what it refuses and what it defaults to.

The packages

Each package is separate, so a program links only what it uses. A dune file names a library as it is installed (rowtype-postgres); OCaml code names it as a module (Rowtype_postgres).

Package	Libraries	What it is
rowtype	rowtype	Queries described once; links no database library
rowtype-postgres	rowtype-postgres	The Postgres backend, over postgres-eio
rowtype-sqlite	rowtype-sqlite	The SQLite backend, over the sqlite3 binding
rowtype-migrate	rowtype-migrate, rowtype-migrate.postgres, rowtype-migrate.sqlite	The migrations and the rowtype-migrate command, for each dialect installed beside it

rowtype

• Rowtype – shapes, statements, errors, and the signature a backend fills.
• Rowtype_postgres – connections, the pool, notifications, transactions, COPY and verify on Postgres. Its parts: Pool, Listener and Transaction.
• Rowtype_sqlite – connections, the pool, transactions, the load and verify on SQLite. Its parts: Pool and Transaction.
• Rowtype_migrate – the files, the record and its rules, the same for every dialect.
• Rowtype_migrate_postgres – migrating Postgres.
• Rowtype_migrate_sqlite – migrating SQLite.

What it is built on

• Postgres_eio – the driver under rowtype-postgres, whose connection strings, pool and listener it passes through.
