pub struct Piece(/* private fields */);Expand description
A piece of archival history in Subspace Network.
This version is allocated on the heap, for stack-allocated piece see PieceArray.
Internally piece contains a record and corresponding witness that together with segment commitment of the segment this piece belongs to can be used to verify that a piece belongs to the actual archival history of the blockchain.
