HashChain

pathfinder_crypto::hash::pedersen

Struct HashChain 

Source 
pub struct HashChain { /* private fields */ }
Expand description

HashChain is the structure used over at cairo side to represent the hash construction needed for computing the class hash.

Empty hash chained value equals H(0, 0) where H is the pedersen_hash() function, and the second value is the number of values hashed together in this chain. For other values, the accumulator is on each update replaced with the H(hash, value) and the number of count incremented by one.
