# `QuackDB.Ecto.Struct`
[🔗](https://github.com/elixir-vibe/quackdb/blob/main/lib/quack_db/ecto/struct.ex#L2)

DuckDB STRUCT expression helpers for Ecto queries.

Natural names are available when importing this module directly. With
`use QuackDB.Ecto`, ambiguous names such as `contains/2`, `extract/2`,
`values/1`, `position/2`, and `concat/2` are excluded; use the explicit
aliases instead.
