DripDrop.DBHelpers (DripDrop v0.1.0)

Small helpers for crossing raw SQL and Ecto schema boundaries.

Repo.query/3 uses Postgrex types directly, while Ecto schemas expose UUIDs as canonical strings. These helpers keep that conversion in one place.

Summary

dump_uuid(uuid)

Converts an Ecto UUID string into the 16-byte form expected by $uuid params.

load_uuid(uuid)

Converts a raw 16-byte UUID returned by Postgrex into an Ecto UUID string.

@spec dump_uuid(term()) :: term()

Converts an Ecto UUID string into the 16-byte form expected by $uuid params.

Values that are already dumped, invalid, or non-binary are returned unchanged so callers can safely pass through database-driver values.

@spec load_uuid(term()) :: term()

Converts a raw 16-byte UUID returned by Postgrex into an Ecto UUID string.
