Struct IdCred

#[repr(C)]
pub struct IdCred {
    pub bytes: BufferIdCred,
}

A value of ID_CRED_x: a credential identifier.

Possible values include key IDs, credentials by value and others.

let short_kid = IdCred::from_encoded_value(&hex!("17")).unwrap(); // 23
assert_eq!(short_kid.as_full_value(), &hex!("a1044117")); // {4: h'17'}
let long_kid = IdCred::from_encoded_value(&hex!("43616263")).unwrap(); // 'abc'
assert_eq!(long_kid.as_full_value(), &hex!("a10443616263")); // {4: 'abc'}

Fields

bytes: BufferIdCred

The value is always stored in the ID_CRED_x form as a serialized one-element dictionary; while this technically wastes two bytes, it has the convenient property of having the full value available as a slice.

Implementations

impl IdCred

pub fn new() -> Self

pub fn from_full_value(value: &[u8]) -> Result<Self, EDHOCError>

pub fn from_encoded_value(value: &[u8]) -> Result<Self, EDHOCError>

Instantiate an IdCred from an encoded value.

pub fn as_full_value(&self) -> &[u8]

View the full value of the ID_CRED_x: the CBOR encoding of a 1-element CBOR map

This is the value that is used when ID_CRED_x has no impact on message size, see RFC 9528 Section 3.5.3.2.

pub fn as_encoded_value(&self) -> &[u8]

View the value as encoded in the ID_CRED_x position of plaintext_2 and plaintext_3.

Note that this is NOT doing CBOR encoding, it is rather performing (when applicable) the compact encoding of ID_CRED fields. This style of encoding is used when ID_CRED_x has an impact on message size.

pub fn reference_only(&self) -> bool

pub fn item_type(&self) -> IdCredType

pub fn get_ccs(&self) -> Option<Credential>

Trait Implementations

impl Clone for IdCred

fn clone(&self) -> IdCred

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdCred

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

Formats the value using the given formatter.

impl Default for IdCred

fn default() -> IdCred

Returns the “default value” for a type.

impl PartialEq for IdCred

fn eq(&self, other: &IdCred) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
