omit_unused_structs ignores enum when used with sqlc.embed #2860

Version

1.22.0

What happened?

When omit_unused_structs is set to true, enums inside an sqlc.embed is ignored. This can cause invalid golang code due to undefined type on the model.

Can be circumvented by creating another query without embed just so the enum model exists in the generated code.

Relevant log output

check generated models.go

Database schema

CREATE TYPE enumtype AS ENUM('a','b');

CREATE TABLE authors (
  id   BIGSERIAL PRIMARY KEY,
  e enumtype not null
);

SQL queries

-- name: GetAllAuthors :one
SELECT sqlc.embed(authors) FROM authors;
