Struct ProofCalculator 

Source 
pub struct ProofCalculator<TC, HC, VE: LeafValueEncoder> { /* private fields */ }
Expand description

A proof calculator that generates merkle proofs using only leaf data.

The calculator:

  • Accepts one or more B256 proof targets sorted lexicographically
  • Returns proof nodes sorted lexicographically by path
  • Automatically resets after each calculation
  • Re-uses cursors from one calculation to the next

Implementations§

Source§

impl<TC, HC, VE: LeafValueEncoder> ProofCalculator<TC, HC, VE>

Source

pub const fn new(trie_cursor: TC, hashed_cursor: HC) -> Self

Create a new ProofCalculator instance for calculating account proofs.

Source§

impl<TC, HC, VE> ProofCalculator<TC, HC, VE>

Source

pub fn proof( &mut self, value_encoder: &VE, targets: impl IntoIterator<Item = Nibbles>, ) -> Result<Vec<ProofTrieNode>, StateProofError>

Generate a proof for the given targets.

Given lexicographically sorted targets, returns nodes whose paths are a prefix of any target. The returned nodes will be sorted lexicographically by path.

§Panics

In debug builds, panics if the targets are not sorted lexicographically.
