# Daemon API

To communicate with the daemon start by connecting to the socket it exposes.
This opens a long-lasting connection that can be used to send RPC messages. The
following messages are planned:

#### `mail::listen-receive`

```
(account : Option<String>) -> Stream<MessageNotification>
```

Begin subscribing to when mail is received for a particular account if provided,
or all accounts by default.

#### `mail::send`

```
(message : SendMessage) -> Result<()>
```

Send an email. If the send fails the result is returned immediately without
retry.

TODO: send with retry?

#### `mail::search`

```
(query : StructuredQuery) -> Result<SearchResultPage>
```

Search for messages, returns a summary of messages + first sentence.
