Implementations§
source§impl PieceSpec
impl PieceSpec
sourcepub fn compute_packing(
&self,
tree_len: usize,
) -> Result<(Vec<(usize, usize)>, usize)>
pub fn compute_packing( &self, tree_len: usize, ) -> Result<(Vec<(usize, usize)>, usize)>
compute_packing
returns a packing list and a proof size.
A packing list is a pair of (start, length) pairs, relative to the beginning of the piece,
in leaf units.
Proof size is a number of elements (size same as one leaf) provided in the variable part of a PieceInclusionProof.
