Struct BufferBudget 

pub struct BufferBudget { /* private fields */ }

What one connection may hold in FrameDecoder payload buffers, as a counter every request stream on it shares (D77).

MAX_BUFFERED_FRAME is per frame and so per stream; this is the sum over the streams, which is the number a peer opening many of them actually controls. super::HEADERS_BUFFER_BUDGET says why that distinction is worth a counter and how the value was chosen.

Every request stream’s decoder holds the same one, so a share taken on any of them is a share the others cannot take. Charging happens when a decoder commits to buffering a frame and releasing when that frame completes or its decoder is dropped, so the counter reads zero on a connection with nothing half-received on it.
