Typed results for platform effect responses.

Every Plushie.Event.EffectEvent carries a result field whose shape is one of the structs defined here. Apps pattern-match on the struct module for richly typed access to the effect outcome, rather than digging into a generic map.

Variants

Success:

• %FileOpened{path: path} - file_open
• %FilesOpened{paths: paths} - file_open_multiple
• %FileSaved{path: path} - file_save
• %DirectorySelected{path: path} - directory_select
• %DirectoriesSelected{paths: paths} - directory_select_multiple
• %ClipboardText{text: text} - clipboard_read / clipboard_read_primary
• %ClipboardHtml{html: html, alt_text: alt_text} - clipboard_read_html
• %ClipboardWritten{} - any clipboard write
• %ClipboardCleared{} - clipboard_clear
• %NotificationShown{} - notification

Non-success:

• %Cancelled{} - the user dismissed the dialog
• %Timeout{} - no response within the kind's timeout
• %Error{message: message} - platform error
• %Unsupported{} - this backend doesn't support the effect
• %RendererRestarted{} - the renderer was restarted while the effect was pending

Pattern matching

def update(model, %Plushie.Event.EffectEvent{
  tag: :import,
  result: %Plushie.Effect.Result.FileOpened{path: path}
}) do
  load_file(model, path)
end

def update(model, %Plushie.Event.EffectEvent{
  tag: :import,
  result: %Plushie.Effect.Result.Cancelled{}
}) do
  model
end

The legacy tuple shape {:ok, value} / :cancelled / {:error, reason} is no longer emitted. Pre-1.0, there is no back-compat layer.
