Struct cbored::Negative

pub struct Negative(_);

CBOR Negative value

Implementations

impl Negative

pub fn raw_value(self) -> Value

Get the underlying Value for this Negative value

pub fn negative_u64(self) -> u64

Extract the negative CBOR value into an unsigned value, which represent the integer : -1 - value

pub fn to_i64(self) -> Option<i64>

Try to convert a negative CBOR number into a i64 representing the value

Note this operation might fail as the CBOR representation can represent any negative number between -1 and -(2^64-1), whereas i64 represent a number between -(2^63) to 2^63-1

pub fn canonical(v: u64) -> Self

Create a canonical Negative element from a u64 that represent the CBOR integer -1 - value, taking the smallest possible CBOR representation

To represent the CBOR negative value -1, Negative::canonical(0)

pub fn is_canonical(self) -> bool

Check if the encoded Negative CBOR element have the smallest representation possible (canonical)

Trait Implementations

impl Clone for Negative

fn clone(&self) -> Negative

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Negative

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

Formats the value using the given formatter.

impl Encode for Negative

fn encode(&self, writer: &mut Writer)

impl PartialEq<Negative> for Negative

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

This method tests for self and other values to be equal, and is used by ==.

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

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