function BigPipe::renderPlaceholder

Renders a placeholder, and just that placeholder.

BigPipe renders placeholders independently of the rest of the content, so it needs to be able to render placeholders by themselves.

Parameters

string $placeholder: The placeholder to render.

array $placeholder_render_array: The render array associated with that placeholder.

Return value

array The render array representing the rendered placeholder.
