Enum Label 

pub enum Label {
    Int(i64),
    Text(String),
}

A COSE label may be either a signed integer value or a string.

Variants

Int(i64)

Text(String)

Implementations

impl Label

pub fn cmp_canonical(&self, other: &Label) -> Ordering

Alternative ordering for Label, using the canonical ordering criteria from RFC 7049 section 3.9 (where the primary sorting criterion is the length of the encoded form), rather than the ordering given by RFC 8949 section 4.2.1 (lexicographic ordering of encoded form).

Panics

Panics if either Label fails to serialize.

Trait Implementations

impl AsCborValue for Label

fn from_cbor_value(value: Value) -> Result<Label, CoseError>

Convert a Value into an instance of the type.

fn to_cbor_value(self) -> Result<Value, CoseError>

Convert the object into a Value, consuming it along the way.

impl CborSerializable for Label

fn from_slice(slice: &[u8]) -> Result<Self, CoseError>

Create an object instance from serialized CBOR data in a slice. This method will fail (with CoseError::ExtraneousData) if there is additional CBOR data after the object.

fn to_vec(self) -> Result<Vec<u8>, CoseError>

Serialize this object to a vector, consuming it along the way.

impl Clone for Label

fn clone(&self) -> Label

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Label

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

Formats the value using the given formatter.

impl Ord for Label

Manual implementation of Ord to ensure that CBOR canonical ordering is respected.

Note that this uses the ordering given by RFC 8949 section 4.2.1 (lexicographic ordering of encoded form), which is different from the canonical ordering defined in RFC 7049 section 3.9 (where the primary sorting criterion is the length of the encoded form)

fn cmp(&self, other: &Label) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Label

fn eq(&self, other: &Label) -> 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.

impl PartialOrd for Label

fn partial_cmp(&self, other: &Label) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
