Module neptune::poseidon

Poseidon hash

Structs

• Poseidon
  Holds preimage, some utility offsets and counters along with the reference to PoseidonConstants required for hashing. Poseidon is parameterized by ff::PrimeField and Arity, which should be similar to PoseidonConstants.
• PoseidonConstants
  Holds constant values required for further Poseidon hashing. It contains MDS matrices, round constants and numbers, parameters that specify security level (Strength) and domain separation (HashType). Additional constants related to optimizations are also included.
• SimplePoseidonBatchHasher

Enums

• HashMode

Constants

• DEFAULT_HASH_MODE

Traits

• Arity
  Available arities for the Poseidon hasher.
