# `FFix.Runner.Result`
[🔗](https://github.com/akash-akya/ffix/blob/v0.2.0/lib/ffix/runner/result.ex#L1)

The outcome and captured output of an execution.

`FFix.run/2` returns this value on success. On failure, it is available as
the `result` field of `FFix.Runner.Error`. Streaming includes it in the exit event.

- `exit_status` — zero for success; a non-zero status for failure.
- `stdout`, `stderr` — captured bytes according to `FFix.Runner.run/2` options;
  `nil` when discarded.
- `last_progress` — latest parsed progress update, when available.
- `argv`, `shell` — the executed arguments and their shell-quoted representation.
- `command` — original command data, or `nil` for raw argv.
- `started_at`, `finished_at`, `duration_ms` — execution timing.

Full stderr collection retains all diagnostic output in memory; use a bounded
tail for long-running commands. Stderr is preserved as raw bytes, not parsed logs.

# `exit_status`

```elixir
@type exit_status() :: non_neg_integer()
```

# `t`

```elixir
@type t() :: %FFix.Runner.Result{
  argv: [String.t()],
  command: FFix.Command.t() | nil,
  duration_ms: non_neg_integer() | nil,
  exit_status: exit_status() | nil,
  finished_at: DateTime.t() | nil,
  last_progress: FFix.Runner.Progress.t() | nil,
  shell: String.t(),
  started_at: DateTime.t() | nil,
  stderr: binary() | nil,
  stdout: binary() | nil
}
```
