Required Methods

fn hash(builder: &mut Builder<C>, input: &[Felt<C::F>]) -> Self::Digest

fn compress(builder: &mut Builder<C>, input: [Self::Digest; 2]) -> Self::Digest

fn assert_digest_eq(builder: &mut Builder<C>, a: Self::Digest, b: Self::Digest)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
