Struct EarlyReplyQueue 

pub struct EarlyReplyQueue<R> { /* private fields */ }

The response stage’s end of the early-reply queue.

Public only so it can be handed to a response stage: it has no method outside the crate, so nothing else can read it. Read only through the crate’s register, which takes a snapshot of what the reader has made visible and then drains the stage’s control channel, and hands back the token that sends the snapshot’s replies. Those made visible since wait for the next snapshot.
