Enum RequestKind 

pub enum RequestKind<'a> {
    Bare,
    Identity {
        spki: &'a [u8],
    },
    Signed {
        spki: &'a [u8],
        nonce: &'a [u8],
        signature: &'a [u8],
    },
}

A classified incoming Binding request (SPEC.md §14.5). Exhaustive: a fourth shape would be a wire-format change requiring a version bump (SPEC.md §12).

Every variant borrows directly from the datagram classify_request was given — nothing here allocates.

Variants

Bare

No DIG attribute at all — an ordinary, uncredentialed Binding request.

Identity

A DIG-IDENTITY alone, with no NONCE and no DIG-SIGNATURE — the first datagram of the client’s challenge/response exchange (SPEC.md §14.9 step 2).

Fields

spki: &'a [u8]

The 91-byte SPKI DER (no version-byte prefix), already shape-validated.

Signed

DIG-IDENTITY + NONCE + DIG-SIGNATURE, in that order, with the signature last.

Fields

spki: &'a [u8]

The 91-byte SPKI DER (no version-byte prefix), already shape-validated.

nonce: &'a [u8]

The NONCE attribute value EXACTLY as carried (base64url text) — the same bytes crate::credential::signing_message expects.

signature: &'a [u8]

The DER-encoded ECDSA signature (no version-byte prefix), already length-validated.
