# `Fil.UnavailableError`
[🔗](https://github.com/pehbehbeh/fil/blob/v0.1.0/lib/fil/exceptions.ex#L149)

The storage didn't answer, or asked to wait. Try again later.

Adapters return it for a timeout, a closed connection, a server error, throttling and too many open files. It's the
only error where retrying may help. `Fil` doesn't retry (for now), because only the caller knows whether a failed
mutation is safe to repeat.

# `t`

```elixir
@type t() :: %Fil.UnavailableError{
  __exception__: term(),
  disk: Fil.Disk.t() | nil,
  op: Fil.Op.name() | nil,
  path: String.t() | nil,
  reason: term()
}
```
