Implementations§

impl<F: PrimeField, A: Arity<F>> HashType<F, A>
sourcepub fn domain_tag(&self) -> F
pub fn domain_tag(&self) -> F
Implements domain separation defined in original Poseidon paper.
Calculates field element used as a zero element in underlying crate::poseidon::Poseidon
buffer that holds preimage.
sourcepub const fn is_supported(&self) -> bool
pub const fn is_supported(&self) -> bool
Some HashTypes require more testing so are not yet supported, since they are not yet needed. As and when needed, support can be added, along with tests to ensure the initial implementation is sound.
