Required Methods

fn hash( builder: &mut Builder<C>, input: &[Felt<SP1Field>], ) -> Self::DigestVariable

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

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

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.
