Struct InspectResult 

#[non_exhaustive]
pub struct InspectResult {
    pub issuer: Option<String>,
    pub subject: Option<String>,
    pub key_id: Option<Vec<u8>>,
    pub algorithm: Option<Algorithm>,
    pub x509_headers: X509Headers,
    pub expires_at: Option<i64>,
    pub cose_type: CoseType,
}

Metadata extracted from a credential without full verification or decoding.

Useful for determining which key to use before calling Decoder::decode(). This allows verifiers in multi-issuer scenarios to:

1. Inspect the credential to find the issuer and key ID
2. Look up the correct verification key
3. Perform full decoding with the appropriate key

Example

use claim169_core::inspect;

let info = inspect(qr_text)?;
println!("Issuer: {:?}, Key ID: {:?}", info.issuer, info.key_id);

// Use the metadata to select the right verification key
let public_key = key_store.get(&info.issuer, &info.key_id);
let result = Decoder::new(qr_text)
    .verify_with_ed25519(&public_key)?
    .decode()?;

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

issuer: Option<String>

Issuer from CWT claims (claim key 1).

subject: Option<String>

Subject from CWT claims (claim key 2).

key_id: Option<Vec<u8>>

Key ID from the COSE header.

algorithm: Option<Algorithm>

COSE algorithm declared in the protected header.

x509_headers: X509Headers

X.509 certificate headers from the COSE structure.

expires_at: Option<i64>

Expiration time from CWT claims (Unix epoch seconds).

cose_type: CoseType

COSE structure type (Sign1 or Encrypt0).
