# `Bylaw.Ecto.Changeset`
[🔗](https://github.com/ryanzidago/bylaw/blob/v0.1.0-alpha.1/lib/bylaw/ecto/changeset.ex#L1)

Extracts conservative changeset candidates from Ecto schema source files.

A candidate is a function whose source AST directly calls `cast/3`,
`cast/4`, `Ecto.Changeset.cast/3`, `Ecto.Changeset.cast/4`, `change/2`, or
`Ecto.Changeset.change/2`. Literal cast/change fields are extracted for
comparison with database constraints. Dynamic field lists are treated as
unverifiable by returning an empty field list for v1.

# `candidates`

```elixir
@spec candidates(paths :: [Path.t()], modules :: [module()]) :: [
  Bylaw.Ecto.Changeset.Candidate.t()
]
```

Returns changeset candidates found for the given schema modules and source paths.
