}

Strongly-typed representation of an RFC 9711 EAT claims-set.

Every field is Option<…> so that only the claims relevant to a particular token need to be populated. Fields whose CBOR value type is composite (map / array) are left as raw ciborium::value::Value so that callers can construct them without an additional indirection layer.

Fields

iat: Option<i64>

Issued-At: seconds since POSIX epoch (CWT key 6).

nonce: Option<Value>

Nonce – eat_nonce (key 10). CBOR value: bstr or array-of-bstr.

ueid: Option<Vec<u8>>

Universal Entity ID – ueid (key 256). A byte string whose first byte encodes the UEID type (0x01 = RAND, 0x02 = IEEE EUI, 0x03 = IMEI, …).

sueids: Option<Value>

Semipermanent UEIDs – sueids (key 257). CBOR value: map of label → bstr.

oem_id: Option<Value>

Hardware OEM ID – oemid (key 258). CBOR value: bstr or int.

hw_model: Option<Vec<u8>>

Hardware Model – hwmodel (key 259). A byte string that uniquely identifies the model within an OEM.

hw_version: Option<Value>

Hardware Version – hwversion (key 260). CBOR value: array [version-string, scheme].

uptime: Option<u64>

Uptime in seconds – uptime (key 261).

oem_boot: Option<bool>

OEM Authorized Boot indicator – oemboot (key 262). true when the booted software is OEM-authorized.

dbg_stat: Option<u64>

Debug Status – dbgstat (key 263). Encoded as a uint; see RFC 9711 Section 4.2.8 for the registry.

location: Option<Value>

Geographic Location – location (key 264). CBOR value: map with optional latitude, longitude, altitude, …

eat_profile: Option<String>

EAT Profile – eat_profile (key 265). A URI or OID identifying the profile this token conforms to.

submods: Option<Value>

Submodules Section – submods (key 266). CBOR value: map of submodule-name → nested-token or claims-set.

boot_count: Option<u64>

Boot Count – bootcount (key 267).

boot_seed: Option<Vec<u8>>

Boot Seed – bootseed (key 268). A byte string that changes on every boot; ties measurements to a single boot cycle.

dloas: Option<Value>

DLOAs – dloas (key 269). CBOR value: array of DLOA maps (Digital Letters of Approval).

sw_name: Option<String>

Software Name – swname (key 270).

sw_version: Option<Value>

Software Version – swversion (key 271). CBOR value: array [version-string, scheme].

manifests: Option<Value>

Software Manifests – manifests (key 272). CBOR value: array of CoSWID or similar manifest structures.

measurements: Option<Value>

Measurements – measurements (key 273). CBOR value: array of measurement maps.

meas_res: Option<Value>

Software Measurement Results – measres (key 274). CBOR value: array of measurement-result maps.

int_use: Option<u64>

Intended Use – intuse (key 275). Encoded as a uint; see RFC 9711 Section 4.2.20 for the registry.

Implementations

impl EatClaimsSet

CBOR encoding and decoding of the claims-set.

pub fn to_cbor_value(&self) -> Value

Serialise the populated fields into a CBOR map (Value::Map).

Only Some(…) fields are emitted; absent claims are omitted from the encoding, consistent with RFC 9711’s optional-claim model.

pub fn to_cbor_bytes(&self) -> Result<Vec<u8>, Box<dyn Error>>

Encode the claims-set to raw CBOR bytes.

pub fn from_cbor_value(value: &Value) -> Result<Self, Box<dyn Error>>

Parse from a CBOR Value::Map representation into EatClaimsSet.

pub fn from_cbor_bytes(bytes: &[u8]) -> Result<Self, Box<dyn Error>>

Decode the claims-set from raw CBOR bytes.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Box<dyn Error>>

Alias for Self::from_cbor_bytes.

Trait Implementations

impl Clone for EatClaimsSet

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EatClaimsSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EatClaimsSet

fn default() -> Self

Returns the “default value” for a type.
