Enum SignerIdentifier 

#[non_exhaustive]
pub enum SignerIdentifier {
    digest(HashedId8),
    certificate(SequenceOfCertificate),
    R_self(()),
}

• @brief This structure allows the recipient of data to determine which
• keying material to use to authenticate the data. It also indicates the
• verification type to be used to generate the hash for verification, as
• specified in 5.3.1.
• @param digest: If the choice indicated is digest:
• • The structure contains the HashedId8 of the relevant certificate. The
• HashedId8 is calculated with the whole-certificate hash algorithm,
• determined as described in 6.4.3.
• • The verification type is certificate and the certificate data
• passed to the hash function as specified in 5.3.1 is the authorization
• certificate.
• @param certificate: If the choice indicated is certificate:
• • The structure contains one or more Certificate structures, in order
• such that the first certificate is the authorization certificate and each
• subsequent certificate is the issuer of the one before it.
• • The verification type is certificate and the certificate data
• passed to the hash function as specified in 5.3.1 is the authorization
• certificate.
• @param self: If the choice indicated is self:
• • The structure does not contain any data beyond the indication that
• the choice value is self.
• • The verification type is self-signed.
• @note Critical information fields:
• • If present, this is a critical information field as defined in 5.2.6.
• An implementation that does not recognize the CHOICE value for this type
• when verifying a signed SPDU shall indicate that the signed SPDU is invalid.
• • If present, certificate is a critical information field as defined in
• 5.2.6. An implementation that does not support the number of certificates
• in certificate when verifying a signed SPDU shall indicate that the signed
• SPDU is invalid. A compliant implementation shall support certificate
• fields containing at least one certificate.
• @note Canonicalization: This data structure is subject to canonicalization
• for the relevant operations specified in 6.1.2. The canonicalization
• applies to every Certificate in the certificate field.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
