Struct Simple 

pub struct Simple(/* private fields */);

A CBOR simple value.

The simple values false, true, null and undefined (20 to 23) map onto the deser data model (undefined is deserialized as null). All other simple values are unassigned and passed through deser as extension atoms of this type. Their fallback is an unsigned integer.

use deser_cbor::Simple;

let bytes = deser_cbor::to_vec(&Simple::new(16).unwrap()).unwrap();
assert_eq!(bytes, [0xf0]);
let value: Simple = deser_cbor::from_slice(&bytes).unwrap();
assert_eq!(value.value(), 16);

Implementations

impl Simple

Trait Implementations

impl Clone for Simple

fn clone(&self) -> Self

fn deserialize_update<'out>( value: &'out mut T, state: &mut State, ) -> SinkHandle<'out, 'de>

Creates a sink that updates an existing value.

impl Eq for Simple

impl Extension for Simple

fn name(&self) -> &str

Returns the human readable name of the extension type.

fn fallback(&self) -> Atom<'_>

Lowers the value into the core data model.

impl Hash for Simple

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Simple

fn cmp(&self, other: &Self) -> 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,
