# `Sig.Repo`
[🔗](https://github.com/peeeuzin/sig/blob/v0.1.0/lib/repo.ex#L1)

Delegates Sig's database calls to your application's Ecto repo.

Sig does not start a repo of its own. Like Oban, it uses the one you
configure:

    config :sig, repo: MyApp.Repo

All of Sig's queries go through this module, which forwards them to that
repo. Since they share the repo, Sig's writes take part in your
transactions, and in tests they use the same SQL sandbox as the rest of your
app.

## Options

  * `:repo` (required) - the `Ecto.Repo` to use.
  * `:prefix` - the PostgreSQL schema where Sig's tables live. Defaults to
    `nil`, which uses the connection's search path (normally `public`). Set
    it to the same prefix you passed to `Sig.Migration.up/1`:

        config :sig, repo: MyApp.Repo, prefix: "sig"

The functions below mirror the `Ecto.Repo` ones of the same name and add
the configured `:prefix` to the options when one is set.

# `prefix`

```elixir
@spec prefix() :: String.t() | nil
```

Returns the configured prefix, or `nil` to use the connection's search path.

# `repo`

```elixir
@spec repo() :: module()
```

Returns the configured repo.

Raises `ArgumentError` if `:repo` is not configured.
