class

RNS::ResourceAdvertisement

Inherits Reference < Object

Encapsulates the metadata exchanged during resource transfer negotiation. Holds transfer size, part count, hashes, flags (encryption, compression, split, request/response), segment info, and the initial hashmap slice. Serialised to/from MessagePack for transmission inside RESOURCE_ADV packets.

Constants

COLLISION_GUARD_SIZE = (2 * Resource::WINDOW_MAX) + HASHMAP_MAX_LEN
HASHMAP_MAX_LEN = ((Link::MDU - OVERHEAD) // Resource::MAPHASH_LEN).to_i32
OVERHEAD = 134
