Detailed Description

One request stream's receive window over a caller-owned BODYWIN_CAP buffer: buf[0] is stream offset base.

Bytes land at their offset (RFC 9000 2.2) when base <= off < base + BODYWIN_CAP; have[] marks which, so only the contiguous prefix (bodywin_frontier) is ever parsed. Consumed bytes slide out, moving the unconsumed tail (a partial frame header, out-of-order bytes) to buf[0]. Zero-initialized = empty at offset 0.

The documentation for this struct was generated from the following file:
