    EditUsernameFragment, the username editor (profile_edit_username, Android 451), opened from the profile editor's Username row. The field shows the account's username; the app asks the server whether the typed name is free while the person types and sends the change on Done.

    Actions:

    • typeUsername(username) is one availability check (users/check_username/). It answers the editor's live handle over what the field now shows — the typed name and the server's check — so the caller continues from it (field = yield* field.typeUsername(name)), as with a search field's keystroke. The handle the action was called on keeps the snapshot the visit loaded.
    • changeUsername(username) sends the change (accounts/update_profile_username/, an unsigned form) and answers the updated user the server returns. The app shows neither a confirmation dialog nor a challenge for it; the profile editor's profile_edit_params carry the dialog's flags, which this screen does not act on.

    The change is not guarded by the check: the app sends the change whatever the last check said, and the server decides.

    How it is reached: EditProfileScreen.openUsername(), the EditUsernameFragment:profile_edit_username:6:button entry over the profile editor. Opening it sends nothing; the change sends the profile editor's reloads.

    No screenshot: the library renders no UI.
