Crate affinidi_oid4vc_core 

Shared types for the OpenID for Verifiable Credentials (OID4VC) protocol family.

This crate provides common types used across SIOPv2, OpenID4VP, and OpenID4VCI:

• ResponseType — protocol response types (id_token, vp_token, code)
• ResponseMode — delivery modes (fragment, direct_post)
• SubjectSyntaxType — subject identifier types (JWK Thumbprint, DID)
• ClientMetadata — Relying Party registration metadata
• DisplayProperties — UI rendering properties
• compute_jwk_thumbprint — RFC 7638 JWK Thumbprint computation
