Enum HashUseAlgorithm 

pub enum HashUseAlgorithm<'a> {
    Digest(DigestAlgorithm),
    Shake256_512,
    Intrinsic(SignatureAlgorithm),
    Unsupported(Option<&'a str>),
}

Declared hash semantics; output length never determines the algorithm.

Variants

Digest(DigestAlgorithm)

A recognized fixed-output digest.

Shake256_512

RFC 8032 Ed448ph’s SHAKE256 prehash with a 64-byte output.

Intrinsic(SignatureAlgorithm)

No independently selected external digest (e.g. PureEdDSA or pure ML-DSA).

Unsupported(Option<&'a str>)

Original unimplemented/malformed instruction, including an absent URI.
