# `WardrikStore.Ecto`

Keeps keys in a Postgres table.

    # Through your app's repo
    store = WardrikStore.Ecto.new(repo: MyApp.Repo)
    children = [MyApp.Repo, {WardrikStore, store}]

    # Through a repo of its own
    store = WardrikStore.Ecto.new(url: "postgres://user:pass@db.example.com/wardrik?ssl=true")
    children = [{WardrikStore, store}]

## Your repo

Create the table from a migration of your own. See `WardrikStore.Ecto.Migration`.

If the table is missing, the store logs an error as it starts. Your app still boots, so a
release can run its migrations.

## A repo of its own

The store starts `WardrikStore.Ecto.Repo` over the URL. It creates the table before it keeps
anything, one node at a time.

`?ssl=true` connects over TLS, verified against the system's certificates. It needs
`:postgrex` in your deps.

# `new`

```elixir
@spec new(keyword()) :: WardrikStore.t()
```

Builds a store. Starts nothing.

## Options

Give one of:

  * `:repo` - your app's repo. Point it at the primary, not a replica.
  * `:url` - a Postgres URL for a repo of its own.

Raises `ArgumentError` if given both or neither.

# `start_link`

```elixir
@spec start_link(module()) :: :ignore
```

Checks the store's table exists in `repo`. Logs an error if it doesn't. Returns `:ignore`.
