Struct StreamRestorer 

pub struct StreamRestorer { /* private fields */ }

Restores one block of streamed model text.

Text is released as soon as it cannot be part of a placeholder. A tail that could still become one (for the default format, an open [ followed only by placeholder characters) is held until it completes, stops matching, grows past the longest possible placeholder, or StreamRestorer::finish is called.

It holds no reference to the engine, so it can live inside a long-running response stream; the engine and scope are passed to each call.
