Struct Pending 

pub struct Pending { /* private fields */ }

One accepted request that has not finished, released when dropped.

The companion to Slot, and deliberately not the same thing: a slot is rationed and is taken only once a request has proved it deserves one, while this is taken the moment the request stream is accepted and rations nothing. What it buys is the drain being able to see a request that is between those two points — headers still arriving, credentials being checked — which is exactly the request a tunnel-count drain used to close the connection on, against the “might have been processed” its own GOAWAY identifier had just signalled (RFC 9114 §5.2).

Dropping is the only way it is given back, for the reason Slot gives.
