pub const DEFAULT_REPLY_QUEUE_DEPTH: u16 = 16;Expand description
Fallback queue depth applied at the pacing-wrapper construction site
when a channel’s reply_queue_depth_max is left at 0. Sized for the
AI-pacing use case: a paced channel buffering more than this is a sign
the agent is producing replies faster than the floor will ever drain
them and the overflow log is the right signal.
