Description
TTL
uint32 TTL must be larger than zero, it decreased in every NeoFS Node
Epoch
uint64 Epoch for user can be empty, because node sets epoch to the actual value
Version
uint32 Version defines protocol version TODO: not used for now, should be implemented in future
Raw
bool Raw determines whether the request is raw or not
