@type memory() :: %{
  :id => String.t(),
  :text => String.t(),

  optional(:updated_at_ms) => non_neg_integer()
}
```

# `namespace_entries`

```elixir
@spec namespace_entries(String.t()) :: [memory()]
```

Returns all memory entries in a namespace.

# `recall`

```elixir
@spec recall(String.t(), String.t(), keyword()) :: [map()]
```
