Module poseidon2 

This module contains the Poseidon hash (whitepaper) function implemented as a Sponge Function.

Poseidon permutation here follows referenced in whitepaper original rust implementation with slight improvements.

Important Usage Notes

This interface provides low-level primitives and does not implement padding or domain separation. Users are responsible for:

• Padding inputs appropriately
• Prepending domain separation tags when needed
• Managing absorb/squeeze transitions correctly
• Ensuring proper security practices for their specific use case

Modules

instance

This module contains the poseidon hash instances for some popular finite field instances.

params

This module contains a trait with poseidon hash parameters.

Structs

Poseidon2

Poseidon2 sponge that can absorb any number of F field elements and be squeezed to a finite number of F field elements.

Enums

Mode

Determines whether poseidon sponge in absorbing or squeezing state. In squeezing state, sponge can only squeeze elements.
