Module capsule 

Available on crate features http and std only.

Bounded, incremental Capsule Protocol decoding (RFC 9297 §3).

Input arrives in arbitrary Bytes chunks, exactly as a data stream delivers it. Capsule Values are never collected unless the application asked for them: DATAGRAM payloads up to CapsuleConfig::max_datagram_size and registered control capsules up to CapsuleConfig::max_capsule_size. Everything else is skipped or, for intermediaries, streamed as it arrives, so flow-control credit is always released (RFC 9297 §3.2, §3.5).
