This package contains a set of helper functions for working with the diesel database crate.

Specifically, it contains:

• various define_sql_function!() calls to define SQL functions to be used in Diesel queries (e.g. lower(), floor(), etc.)

• a deserialization helper for semver::Version

• a pg_enum!() macro to define an enum based on a PostgreSQL integer column

This package was extracted from the main application to avoid repeated recompilation of these macros when the main application is recompiled.
