reth_trie::proof

Struct Proof

Source 
pub struct Proof<T, H> { /* private fields */ }
Expand description

A struct for generating merkle proofs.

Proof generator adds the target address and slots to the prefix set, enables the proof retainer on the hash builder and follows the same algorithm as the state root calculator. See StateRoot::root for more info.
