Struct Sha256Hex 

pub struct Sha256Hex(/* private fields */);

A SHA-256 digest, normalised to 64 lowercase hex characters.

Parsed rather than compared as a raw string so that a malformed published value — the wrong length, a non-hex character, an sha256: prefix — is a refusal rather than a comparison that quietly never matches. A digest check that can never succeed and a digest check that can never fail are the same defect wearing different clothes.
