Data Fields
const uint8_t *	head
	Sniffed bytes to replay.
size_t	head_len

void *	inner_ctx
	Context for the source.

Detailed Description

Pull adapter that replays the sniffed head bytes, then delegates.

The producer must peek the source magic before choosing a decoder, but every decoder expects the stream from byte 0; this adapter serves the peeked bytes first, then transparently delegates to the inner source. Shared so the WebP arm can pull its whole compressed source through the same replay as the streaming decoders.

Invariant

pos <= head_len at all times.
